Dynamically Rendering AlloyUI Modal body HTML via Javascript

Question

I have a form created via javascript that will be set as the content of a modal widget provided by Alloy UI . However I don't feel I am approaching this the right way. This question applies for javascript-created HTML in general.

I realize I should avoid using global variables for the sake of namespace and collision, so maybe someone can help me out. I declare the global var myForm and initialize it with some HTML elements to create a form:

var myForm = '<form id="my-form" method="get"> 
<div> 
  <select> 
    <option value="option-1">Option 1</option> 
    <option value="option-2">Option 2</option> 
    <option value="option-3">Option 3</option> 
  </select> 
</div> 
</form>'

And a modal widget that sets myForm as the body content:

var modal = new Y.Modal(
    {
        bodyContent: myForm,
        centered: true,
        modal: true,
        resizable: false,
        draggable: false,
        width: 350
    }).render();

This seems like a not-so-great way of using Javascript to render HTML, especially for my project since I will have many html elements created via javascript ( <img> 's, <ul> 's etc), so I don't want to get into a bad coding habit. Is there a more standard or acceptable way to dynamically render HTML (not speaking from a templating perspective, ie, Thymeleaf, etc)? Thanks all

An alternative solution is to specify the modal and it's contents in your html, and then let AlloyUI take over and turn it into a modal dialog. You can do this by specifying the boundingBox and contentBox of the Modal as the div s which contain the html you want inside the modal:

 YUI().use('aui-modal', function(Y) { new Y.Modal({ boundingBox: '#bb', contentBox: '#cb', centered: true, modal: true, resizable: false, draggable: false, width: 350 }).render(); });

我会在脚本标记内声明模板，如下所述： <script type =“text / template”> ... </ script>的解释
