The j:while tag

The j:while tag is used to perform the while loop. The while loop continues till the test expression condition evaluates to true. The while loop breaks once the condition evaluates to false. We can also manually break out of the j:while loop using the j:break tag. The j:while tag accepts the following attributes:

• test: This is used to specify the Jelly expression (condition) to evaluate. If the expression evaluates to true, the body of the tag is evaluated.

For example:

<g:evaluatevar="jvar_gr" object="true"> 
  var gr = new GlideRecord("incident"); 
  gr.addQuery("active", true); 
  gr.query(); 
  gr; 
</g:evaluate> 
<ul> 
  <j:while test="${jvar_gr.next()}"> 
    <li>${jvar_gr.getValue('number')}</li> 
</j:while> 
</ul>
