i'm trying to do this code, but doesn't working:
function iframeLoad(iframe) {
var body = $(iframe).contents().find('body');
html2canvas(body, {
onrendered: function( canvas ) {
alert(canvas.toDataURL());
//this alert doesn't working
},
allowTaint: true,
taintTest: false,
logging: true
});
}
If a change the var "body" to body on my page (not iframe), it works:
var body = $('body');
Thanks :D

I have the following code, which works fine except for the "makeToast" function that I'm trying to call when status response is true. I get a "this.makeToast is not a function" error on the console.
This function is working fine if I call it after the XMLHttpRequest code. The data is also not being assigned to the msgForm property. I could not figure out why. The "alert(..." message work fine.
<script>
import ToastMixins from '/src/mixins/ToastMixins'
let config = {
headers: {
}
}
export default {
name: 'ModalDestaque',
mixins: [
ToastMixins
],
methods: {
myFunction() {
xhr.onreadystatechange = function () {
if (xhr.readyState === 4) {
console.log('onreadystatechange');
console.log('responseText 1', xhr.responseText);
this.loading = false;
if (xhr.status == 200) {
console.log('responseText 2', xhr.responseText);
let responseObj = JSON.parse(xhr.responseText);
console.log('responseObj', responseObj);
if (responseObj.status == true) {
//alert('Ok');
// this is not working:
this.msgForm = "Message success!";
this.makeToast('b-toaster-bottom-right', true, 'success');
} else {
alert('Not ok...');
}
}
}
};
}
}
}
What am I doing wrong?
I've found the solution while reading the docs at W3 Schools.
W3 Schools AJAX XMLHttp - Multiple Callback Functions
Although, I haven't found a working example anywhere.
In my code, at the button click event that triggers the XMLHttpRequest, I've added the function name "callToast" as a variable, so:
#click="onClickSubmit(myValue, myId, myTitle, callToast)"
Then in the script:
<script>
onClickSubmit(amount, id, title, cFunction) {
// stuff
if (xhr.status == 200) {
let responseObj = JSON.parse(xhr.responseText);
if (responseObj.status == true) {
// here I call the callToast function:
cFunction(this);
alert('Ok');
} else {
alert('Not ok...');
}
}
},
callToast() {
this.msgForm = "Message success!";
this.makeToast('b-toaster-bottom-right', true, 'success');
}
</script>
So I have datetimepicker. And I have datatable like the following code
var table = $("#tbllogvisitor");
var target = table.attr('data-table');
var date = $("#datetimepicker3").data("date");
var oTable = table.on( 'processing.dt', function ( e, settings, processing ){
if (processing) {
$(this).find('tbody').addClass('load1 csspinner');
} else{
$(this).find('tbody').removeClass('load1 csspinner');
};
}).DataTable({
"bServerSide": true,
"paging": false,
"filter": false,
"scrollCollapse": true,
"ordering": false,
"ajax": {
"url" : "../ajax/datatable",
"type": "POST",
"data" :{
target: function() { return target },
tanggal: function() { return date }
}
}
});
Well is working, and then I wanna trigger datetimepicter if I'm changing my datetimepicter value with the following code :
$("#datetimepicker3").on("dp.change", function (e) {
oTable.ajax.reload();
});
But the paramater variable of datetimepicker still not change at all, still same at first time. How do Ii pass my value datetimepicker and reload the datatable?
Sorry for my bad english.
I have a table that shows a pop-up when the first cell is clicked like this:
$('#tblAllUsers tbody').on('click', 'td', function () {
var visIdx = $(this).index();
if (visIdx != 0) {
return false;
}
var par = this.parentNode.parentNode.id;
var oTable = $("#tblAllUsers").dataTable();
var rowIndex = $(this).closest('tr').index();
var aPos = oTable.fnGetPosition(this);
var aData = oTable.fnGetData(aPos[0]);
var name = aData[1];
if (name != '') {
GetUser(name, rowIndex, "#tblAllUsers");
}
else {
ErrorDialog("#MessageDialog", "#lblError", "The User ID is blank in that row.", "No User ID");
return false;
}
});
The pop-up allows the user to modify fields and save it, close the dialog and then return to the grid. If the dialog is canceled, data not saved, the scroll is maintained. But if the data is saved, and I am not reloading the table, the table moves to the top. The AJAX update function is within the pop-up:
$.ajax({
type: 'POST',
data: $("#formUserModification").serializeArray(),
url: '#Url.Action("UpdateUser")',
success: function (data) {
if (data.Errors === 'ERROR') {
ErrorDialog("#MessageDialog", "#lblError", "There was an error encountered in modifying the user, please try again later.", "Error");
}
else {
updateTable(data);
}
$("#divDetails").dialog('close');
},
beforeSend: function () {
$("#divOverlay").show();
},
complete: function () {
$("#divOverlay").hide();
}
});
The update function simply loads the row:
function updateTable(data) {
var tab = $("#tblAllUsers").dataTable();
tab.fnUpdate(data.LastName + ', ' + data.FirstName, data.RowIndex, 0);
tab.fnUpdate(data.ID, data.RowIndex, 2);
tab.fnUpdate(data.LocationText, data.RowIndex, 3);
tab.fnUpdate(data.SiteText, data.RowIndex, 4);
}
Is there a way with this setup to keep the scroll position?
I accomplished my goal by doing this:
Define a variable:
var scrollToPos;
In the dialog definition set the value when it is opened and place the scroll bar when it is closed:
$("#divAllUsersDetail").dialog({
autoOpen: false,
width: '90%',
resizable: false,
draggable: false,
title: 'Details',
position: { my: 'top', at: 'top+100' },
modal: true,
closeOnEscape: false,
open: function() {
scrollToPos = $("#divAllUsers").find(".dataTables_scrollBody").scrollTop();
},
close: function () {
$("#divAllUsers").find(".dataTables_scrollBody").scrollTop(scrollToPos);
},
show: {
effect: 'drop', direction: 'up'
},
hide: {
effect: 'fade', duration: 200
},
buttons: {
"Cancel": function () {
$(this).dialog("close");
}
}
}).prev("ui-dialog-titlebar").css("cursor", "default");
This works famously.
A contrived example of bi-directional data binding
var user = {
model: function(name) {
this.name = m.prop(name);
},
controller: function() {
return {user: new user.model("John Doe")};
},
view: function(controller) {
m.render("body", [
m("input", {onchange: m.withAttr("value", controller.user.name), value: controller.user.name()})
]);
}
};
https://lhorie.github.io/mithril/mithril.withAttr.html
I tried the above code does not work nothing.
It was the first to try to append the following.
m.mount(document.body, user);
Uncaught SyntaxError: Unexpected token n
Then I tried to append the following.
var users = m.prop([]);
var error = m.prop("");
m.request({method: "GET", url: "/users/index.php"})
.then(users, error);
▼/users/index.php
<?php
echo '[{name: "John"}, {name: "Mary"}]';
Uncaught SyntaxError: Unexpected token n
How do I operate the m.withAttr tutorials code?
Try returning m('body', [...]) from your controller.
view: function (ctrl) {
return m("body", [
...
]);
}
render should not be used inside of Mithril components (render is only used to mount Mithril components on existing DOM nodes).
The example is difficult to operate because it's contrived, it's not meant to be working out-of-the-box. Here's a slightly modified, working version:
http://jsfiddle.net/ciscoheat/8dwenn02/2/
var user = {
model: function(name) {
this.name = m.prop(name);
},
controller: function() {
return {user: new user.model("John Doe")};
},
view: function(controller) {
return [
m("input", {
oninput: m.withAttr("value", controller.user.name),
value: controller.user.name()
}),
m("h1", controller.user.name())
];
}
};
m.mount(document.body, user);
Changes made:
m.mount injects html inside the element specified as first parameter, so rendering a body element in view will make a body inside a body.
Changed the input field event to oninput for instant feedback, and added a h1 to display the model, so you can see it changing when the input field changes.
Using m.request
Another example how to make an ajax request that displays the retrieved data, as per your modifications:
http://jsfiddle.net/ciscoheat/3senfh9c/
var userList = {
controller: function() {
var users = m.prop([]);
var error = m.prop("");
m.request({
method: "GET",
url: "http://jsonplaceholder.typicode.com/users",
}).then(users, error);
return { users: users, error: error };
},
view: function(controller) {
return [
controller.users().map(function(u) {
return m("div", u.name)
}),
controller.error() ? m(".error", {style: "color:red"}, "Error: " + controller.error()) : null
];
}
};
m.mount(document.body, userList);
The Unexpected token n error can happen if the requested url doesn't return valid JSON, so you need to fix the JSON data in /users/index.php to make it work with your own code. There are no quotes around the name field.
The following code is a confirm dialog that contains "OK" and "Cancel" button, I would like to retrieve the value either user selected "OK" or "Cancel".
dojo.provide("custom.dialog.ConfirmDialog");
dojo.declare("custom.dialog.ConfirmDialog",dijit.Dialog , {
message : "",
postCreate: function(){
var self = this;
this.inherited(arguments);
this.contentCenter = new dijit.layout.ContentPane({ content : this.message, region: "center"});
this.contentBottom = new dijit.layout.ContentPane({region: "bottom"});
this.okButton = new dijit.form.Button( { label: "OK" } );
this.cancelButton = new dijit.form.Button( { label: "Cancel" } );
this.contentBottom.addChild(this.okButton);
this.contentBottom.addChild(this.cancelButton);
this.addChild(this.contentCenter);
this.addChild(this.contentBottom);
this.okButton.on('click', function(e){
self.emit('dialogconfirmed', { bubbles: false } );
self.destroy();
return "OK";
});
this.cancelButton.on('click', function(e){
self.emit('dialogdeclined', { bubbles: false } );
self.destroy();
return "Cancel";
});
}
});
But there was nothing returned, please help me out if you can point out my mistake, thanks!
You are trying to access the value in event listener? You can pass the label as part of the arguments.
self.emit('dialogconfirmed',
{ bubbles: false, label: self.okButton.get('label') } );
Usage:
this.confirmDialog.on('dialogconfirmed', function(data) {
var label = data.label;
});
