writing a tampermonkey script, grabbed an htmlcollection of all td's on the page with getElementsByTagName, returning 400+ tds. go to step through those to examine the contents of each td.. and debug console in browser is showing TypeError: Cannot read properties of undefined (reading 'innerText') or 'innerHTML' when I swap those two out. obv, I am referencing the items in the collection incorrectly, but I thought I was following examples...
var cells = document.getElementsByTagName("td");
var cellvalue = "example";
/* steps through all the items in the array looking at each one individually */
for (let i = 0; 1 < cells.length; i++) {
/* grabs the contents of the td */
cellvalue = cells[i].innerText;
I tried using .innerText, .innerHTML, and a few other things but I always get the same TypeError. console logging cells.length is showing correctly finding hundreds of tds, but I cant seem to reference them properly.

I have an MFC SDI application to display a list of data read from a csv file. So I set up its view to be inherited from CListView and make it a virtual list control. That means I have to use LVS_OWNERDATA as one of its CListCtrl style attributes. Yet I now run into a problem when I have to include Checkboxes in each row of the displayed list. As you might know, LVS_EX_CHECKBOXES can't be used with LVS_OWNERDATA, I therefore create a bitmap file to contain 2 small images of checkbox (selected and de-selected) and toggle them every time the user clicks on the loaded image/icon. I am handling this in OnNMClick method. And I have two problems I would like to ask for your help to solve.
(1) I don't know how to update the virtual list (which is commonly handled in OnLvnGetdispinfo method) so I try this in OnNMClick and find that the check and unchecked images aren't toggled.
void CMFCSDITest::OnNMClick(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);
// TODO: Add your control notification handler code here
*pResult = 0;
LVHITTESTINFO hitinfo;
hitinfo.pt = pNMItemActivate->ptAction;
int nItem = pListCtrl->HitTest(&hitinfo);
if (hitinfo.flags != LVHT_ONITEMICON)
return;
NMLVDISPINFO *pDispInfo = reinterpret_cast<NMLVDISPINFO*>(pNMHDR);
LV_ITEM* pItem = &(pDispInfo)->item;
if (pItem->iImage == 0)
pItem->iImage = 1;
else
pItem->iImage = 0;
pListCtrl->SetItem(pItem);
pListCtrl->UpdateWindow(); //this is wrong as nothing seems updated after all.
}
Given that the created imagelist is inserted into the pListCtrl already (in OnInitialUpdate method) and I set the output image index value in OnLvnGetdispinfo method.
(2) Instead of handling OnNMClick, I read somewhere people's advice that OnLvnItemchanged method could also be used. However in LPNMLISTVIEW struct, there is uNewState and uOldState variable members for which I don't know how to set up my tiny checked and unchecked icons as status images. Because I might have to do this
if (pNMLV->uChanged & LVIF_STATE)
{
switch (pNMLV->uNewState & LVIS_STATEIMAGEMASK)
{
case image1://do
case image2://do
}
}
I'm trying to use extension for Qlikview 11SR2.
I've tried to access data with this.Data.Rows, but this object is empty even though the data is not empty and I can display the data in a table.
The code I have used is:
var obj = this.Data;
for(var prop in obj) {
var div = document.createElement("div");
div.innerHTML = "" + prop + "" + obj[prop];
this.Element.appendChild(div);
}
I have no access to the internet - I work offline.
How can i make this.Data.Rows contain the data (it is undefined)?
Based on your feedback, I would say it might be worth trying a slightly different way of accessing your data as the this.Data.Rows object contains a collection of row objects which in turn contain one or more objects, which relate to the dimensions and measures passed to the script (and are defined in definition.xml).
For example, say that I have an extension that features a dimension and a measure (in that order). I can access each value of these in a loop as follows:
for (var rowIx = 0; rowIx < this.Data.Rows.length; rowIx++) {
var row = this.Data.Rows[rowIx];
myDimensionValue = row[0].text;
myMeasureValue = row[1].text;
}
I can then add code to output each value of myDimension and myMeasureValue to the loop, such as in your case adding a new div for each set of values.
I found the "QVConsole" extension invaluable when writing extensions, as it allows you to have a JavaScript console in your QlikView document, so you may then use statements like console.log(myDimensionValue) etc. to help you debug your extension. You can download it from https://github.com/thomasfriebel/QvConsole.
In you extension object in the webview, set the dimension and a valid expression. Let me know whether it works!
We have developed a Thunderbird (11) plugin that allows us to save the content of a message to disk. Now we are extending this extension to allow automatic processing of a message when you close it. We run into a number of issues:
We cannot find a way to hook into a 'close tab' event. We are also having trouble getting the Message URI of the currently open tabs (we are trying catching click and keyboard events now). This information does not appear to be available in the DOM of the tab container.
Is there a way to detect closing of a mail message tab or window in a generic way, together with retrieving the URI of the closed mail message for further processing?
We have looked at the documentation of the tab container, the NsIWindowMediator, tried various event listeners, but no luck so far.
Edit: We are getting some results using the most recently closed tabs list. Not a very elegant solution but at least we have a reference to the tab. Now we only have to get the URI to the message that was contained inside the tab.
We cannot find a way to hook into a 'close tab' event.
The (badly documented) <tabmail> element allows registering tab monitors. Something like this should work:
var tabmail = document.getElementById("tabmail");
var monitor = {
onTabClosing: function(tab)
{
...
}
};
tabmail.registerTabMonitor(monitor);
We are also having trouble getting the Message URI of the currently open tabs
The <tabmail> element has a property tabInfo containing information on the currently open tabs. You probably want to look only at the tabs where mode.name is "message" (there is a bunch of other modes as well, e.g. "folder" or "contentTab"). This mode has a getBrowser() method, so something like this should do:
var tabmail = document.getElementById("tabmail");
for (var i = 0; i < tabmail.tabInfo.length; i++)
{
var tab = tabmail.tabInfo[i];
if (tab.mode.name == "message")
alert(tab.mode.getBrowser().currentURI.spec);
}
Edit: As Peter points out in the comments, the approach to get the URI for a message will only work the currently loaded message - all tabs reuse the same browser element for the mail messages. Getting the URI properly is more complicated, you have to get the nsIMsgDBHdr instance for the message via TabInfo.folderDisplay.selectedMessage and then use nsIMsgFolder.getUriForMsg() to construct the URI for it:
var tabmail = document.getElementById("tabmail");
for (var i = 0; i < tabmail.tabInfo.length; i++)
{
var tab = tabmail.tabInfo[i];
if (tab.mode.name != "message")
continue;
var message = tab.folderDisplay.selectedMessage;
alert(message.folder.getUriForMsg(message));
}
For the second part of the question:
The following example code will at provide you the msgDBHdr objects of all opened tabs. You should do some checks on the type to avoid accessing a message in a calendar tab.):
tabInfos = window.document.getElementById("tabmail").tabInfo;
for (i = 0; i < tabInfos.length; i++) {
msgHdr = tabInfos[i].folderDisplay.selectedMessage;
alert(
msgHdr.mime2DecodedSubject+"\n"
+msgHdr.messageId+"\n"
+"in view type "+tabInfos[i].mode.type
);
}
The tabinfo entries have some further interesting information. Just open the ErrorConsole and run
top.opener.window.document.getElementById("tabmail").tabInfo[0].toSource()
and read through it carefully.
I can't seem to use the info returned by fl.findObjectInDocByType() with fl.getDocumentDOM().selection.
I want to use document.setTextRectangle to re-size some text fields from an array generated using fl.findObjectInDocByType().
I can easily access all the textObject properties but since document.setTextRectangle requires a current selection, I am at a loss.
The example in the documentaion for setting selection is:
fl.getDocumentDOM().selection = fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0];
fl.findObjectInDocByType() returns an array of objects with the attributes: (object.timeline, object.layer, object.frame, object.parent)
But these are objects, and don't have a property for array index numbers required by fl.getDocumentDOM().selection=...
var doc = fl.getDocumentDOM();
var textFieldArray = fl.findObjectInDocByType("text", doc);
for (var i=0; i < textFieldArray.length; i ++){
fnResizeTheTextField(textFieldArray[i]);
}
function fnResizeTheTextField(theTextField){
//force current selection to be theTextField
//doc.selection MUST be an array, so assign theTextField to an array...
var selectArray = new Array();
selectArray[0] = theTextField.obj;
var theTimeline =theTextField.timeline;
var theLayer =theTextField.layer;
var theFrame =theTextField.frame;
doc.currentTimeline =theTextField.timeline;
doc.selection = doc.getTimeline().theLayer.theFrame.selectArray;//error
//resize the text rectangle
doc.setTextRectangle({left:0, top:0, right:1000, bottom:1000});
}
}
Result: Error:doc.getTimeline().theLayer has no properties
It turns out, the ObjectFindAndSelect.jsfl script already contains a function specifically for this: fl.selectElement(). Much more elegant:
var doc = fl.getDocumentDOM();
// generate an array of elements of type "text"
var textFieldArray = fl.findObjectInDocByType("text", doc);
for (var i=0; i < textFieldArray.length; i ++){
fnResizeTheTextField(textFieldArray[i]);
}
function fnResizeTheTextField(theTextField){
//force current selection to be theTextField
fl.selectElement(theTextField,false);//enter 'edit mode' =false...
//resize the text rectangle
doc.setTextRectangle({left:0, top:0, right:1000, bottom:1000});
}
}
I found the answer. In order to select anything for a document level operation, you have to also make flash focus on the keyframe of that object.
so, if I loop through an array of objects created by fl.findObjectInDocByType(), I use this code to make flash focus on the object correctly:
function fnMakeFlashLookAt(theObject){
doc.currentTimeline =theObject.timeline;
doc.getTimeline().currentLayer =theObject.layer;
doc.getTimeline().currentFrame =theObject.frame;
}
this may not work on objects nested inside a symbol however.
I had a similar issue recently, and apparently all google results about setTextRectangle() direct us here. It's unbelievable how poorly documented jsfl is :)
If you need to use setTextRectangle() inside an library item that is not on stage, you need to open for edit the item first.
Here's the code that solved my problem:
library.selectItem(libraryItemName);
doc.selection = [tf];//where tf is the reference to textfield we need to edit
doc.library.editItem(libraryItemName);
doc.setTextRectangle({left:l, top:t, right:r, bottom:b});
doc.selectNone();
If you have a better working solution, please post. I hope it saves somebody's time. Good luck!
i have to run following javascript through one of my method. But its not running
Whats wrong with the code.
private void fillGrid1()
{
GridView1.DataSource = myDocCenter.GetDsWaitingForMe(Session["UserID"].ToString());
HiddenField1.Value = { myDocCenter.GetDsWaitingForMe(Session["UserID"].ToString()).Tables[0].Rows.Count).ToString();
GridView1.DataBind();
String csname1 = "PopupScript1";
String csname2 = "ButtonClickScript1";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the client script is already registered.
if (!cs.IsClientScriptBlockRegistered(cstype, csname2))
{
StringBuilder cstext2 = new StringBuilder();
cstext2.Append("<script type=\"text/javascript\"> ");
// You can add JavaScript by using "cstext2.Append()".
cstext2.Append("var count = document.getElementById('ctl00_ContentPlaceHolder1_HiddenField2');");
cstext2.Append("var count = '100';");
cstext2.Append("document.getElementById('sp2').innerHTML = count;");
cstext2.Append("script>");
cs.RegisterClientScriptBlock(cstype, csname2, cstext2.ToString(), false);
}
}
Your script tag is not properly closed.
Change
cstext2.Append("script>");
to
cstext2.Append("</script>");
On top of what adamantium said, your JS looks a bit strange. You seem to declare and set the count variable twice - did you mean to do this.
Following that, best thing to do, render the page then view source. is your JS getting rendered to the page? try and stick an alert in there... is it firing?
> cstext2.Append("var count =
> document.getElementById('ctl00_ContentPlaceHolder1_HiddenField2');");
I would use the ClientID property here. HiddenField2.ClientID
RegisterClientScriptBlock emits the script just after the <form> tag openning. Browser executes this script just after the tag openning as well but referenced elements are not processed yet at this time - browser cannot find them.
RegisterStartupScript method emits the script just before the <form> tag ending. Nearly all page elements are processed by the browser at this place and getElementById could find something.
