I have a dashboard built using dojo dijits. One of the dijit is dojo calendar widget.
In this dashboard I am embedding an iframe to it. I want to change the value of the calendar widget from within the iframe.
The issue is since it is not just about changing the text value in the input box of calendar dijit it is also about calling the on change event. So I am using the following
dijit.byId('dijit_form_DateTextBox_1').set('value', datFrom);
This way the value gets updated as well as the change event is fired.
Now since I want to do this from within the iframe I need to get reference to calendar dijit in parent HTML page.
If this is a simple Javascript I would have used following to get to that DOM Element and change the value.
const targetNode = $('#'+divId, window.parent.document)[0];
But since this is dojo so I am unable to get this as a dijit object. Is there a way to get dijit from Parent page
Since the dataTextBox is inside iframe, it's in different scope, and looks like you are not using dojo in AMD pattern.
What you could do is get the object from iFrame's contentWidow and call byID() like any other function, example
var _dijit = document.getElementById("iframeId").contentWindow.dijit;
var dateTextBox = _dijit.byId('dijit_form_DateTextBox_1');
dateTextBox.set('value', datFrom);
or better is, you just call a global reference your own function rather than taking reference of dijit.

I have 2 components. I have some checkboxes in first component.It resides in left side of the Web Page like Nav bar. In second component I would like to load some HTML Div element on the basis of those checkbox. Now I can load the divs while clicking on those checkboxes using below code.
mounted () {
EventBus.$on('change',this.formated);
},
But when I am clicking on a new checkboxes the loaded divs of previous checkboxes will not disappear. I can see both output of current and previous checkboxes as like output of .append() of jQuery.
How can I clear/disappear previous HTML outputs ?
You need use jQuery's clear() on the elements innerHTML which you're appending too. A better approach would be to instead of appending content, use a v-for directive and maintain an array in the data property with the content you want visible. That would be leveraging vue's reactivity for its intended purposes and offer a more flexible implementation.
I am currently developing a web application that is used to display elements for events on a map provided by HERE Maps. I am using Vue.
I have some components, but the relevant component is the component HereMaps.vue which initializes the map using the HERE Maps Api.
The HERE Maps Api provides the possibility to place so called InfoBubbles on the map showing additional information. These InfoBubbles can be provided some HTML-code in order to customize their appearance.
Please refer to the documentation for additional information
Following the documentation the code looks something like this:
let bubble = new H.ui.InfoBubble(marker.getPosition(), {
content: "<div class='someClass'>Some Content</div>"
});
this.ui.addBubble(bubble)
This is happening after mount in the "mounted" method from Vue in the "HereMaps" component.
The Bubbles are added in a "closed" (hidden) form and dynamically "opened" to reveal their content when the corresponding marker icon on the map is clicked. Therefore the HTML-code is present on the DOM after the component is mounted and is not removed at a later stage.
Now instead of supplying custom code within each bubble added to the UI i want to just add a component like this:
let bubble = new H.ui.InfoBubble(marker.getPosition(), {
content: "<myDynamicComponent></myDynamicComponent>"
});
this.ui.addBubble(bubble)
It does not matter to me wether the component is initialized using props or if it is conditionally rendered depending on the state of a global variable. I just want to be able to use the "myDynamicComponent" in order to customize the appearance in a different file. Otherwise the design process gets very messy.
As far as i know this is not possible or at least i was not able to get it work. This is probably due to the fact that the "myDynamicComponent" is not used within the "template" of the "HereMaps" component und thus Vue does not know that it needs to render something here after the directive is added to the DOM in the "mounted" method.
This is what the InfoBubble looks using normal HTML as an argument:
This is what the InfoBubble looks using the component as an argument:
It appears to just be empty. No content of the "myDynamicComponent" is shown.
Does anyone have any idea how i could solve this problem.
Thank You.
Answer is a bit complicated and I bet you wouldn't like it:)
content param can accept String or Node value. So you can make new Vue with rendered your component and pass root element as content param.
BTW, Vue does not work as you think, <myDynamicComponent></myDynamicComponent> bindings, etc exists in HTML only in compile time. After that all custom elements(components) are compiled to render functions. So you can't use your components in that way.
Give us fiddle with your problem, so we can provide working example:)
I have a seaside application with a master-detail page. The master page has a table that consists of a list of tr records. When the user clicks a particular tr element, I want to call a detail component, which'll show the individual record's data.
Since I cannot make a tr element with callback or have it contain an anchor with a callback, I want the tr's onClick property to have some JavaScript which'll call: subcomponent . When I tried this, I got an error saying call: can only be used in callbacks and tasks.
Using ajax is a workaround, however it breaks the back button.
Edit:
More generally, I'd like to know how to set callback like behaviour for various JavaScript events.
Well, you cannot render a component in a tr element, but you could add some anchor or other element in one of its td children.
For my project I did roughly the following: I added an anchor to each row with a special css class, e.g. '.dblclick-action'. This anchor has a normal Seaside callback.
Then I bound a dblclick handler to the tr element that does something like document.location=$(this).find('.dblclick.ction').get(0).href;
I am not close to a Smalltalk image now to give you source code, but I hope you get the idea: you don't use Ajax to click the link in that particular row, but instead have the browser navigate to the callback that is associated to the link in that row. You could say you use the tr.'s dblclick handler to click the link and then let the normal Seaside stuff do its work. No magic there. You can find a little bit more info here.
If you don't want the anchor to be visible you may want to experiment with making the anchor invisible (display: none) or the like.
If you are a bit more experiment friendly, you can also try saving a callback on the server and render its url with callback id as an attribute of the tr element and use the dblclick handler to follow the link from that attribute you extract the value of an attribute in query using attr().
I forgot to answer your initial question: you cannot issue a call: from javascript. But you can use the document.location trick to re/misuse an existing link to a callback on the page using the technique I described in my first answer.
I need to display content in a lightbox along with recaptcha.This was very easy except that recaptcha can be used only one per page.So, that threw the hidden div option away. Now, iam trying to render the content via js.erb using jquery's html() method. Rest of the content is rendered correctly.But, i'm having trouble rendering recaptcha.Is there a way to render recaptcha via jQuery html() method? I am using Ambethia reCaptcha.
Found a solution. I used a single Div(main lightbox container).Within that div, i added another div which wrapped <%=recaptcha_tags%>.This inner div was placed using absolute positioning.For the rest of the content, i used jquery's append() function instead of html() function.
I have set up in Javascript my preferred dijit.Menu which is that far so good.
How am I able to display the dijit.Menu directly after the page starts up in the (with it's position) without any mouse interaction?! I have looked in the API so far and don't find the answers. Will I have to "overwrite" a method?
If yes, which one is it? And what do I have todo???
The widget will not show up until it is parsed by dojo.
You should place fake menu markup inside its dom node:
<div dojoType="dijit.Menu">
<h1>This text is shown after the dom is loaded
and until the menu is parsed and renered</h1>
</div>
As soon as menu is ready, everything you've placed inside menu's dom node will be replaced by actual widget's html.
