JQuery库中的特殊值

Question

I'm using the JQueryGantt library and looking in the source code I found as value of some <input> element, values like these (#=obj.code?obj.code:''#) . I haven't seen nothing like this in javascript. What are these?

Answer 1

its for the JST jquery template engine, this way you can access properties of the object, in this case a "TASKROW" and renders the value, check the lines 30 to 47 to see how it is parsed and executed

https://github.com/robicch/jQueryGantt/blob/52bc859bab0866a45b2e233b5783ed8d7046ae4b/libs/jquery/JST/jquery.JST.js

the object is defined for usuage with the templating engine

var taskRow = $.JST.createFromTemplate(task, "TASKROW");

and in the template you see

<div class="__template__" type="TASKROW"><!--
  <tr taskId="(#=obj.id#)" class="taskEditRow (#=obj.isParent()?'isParent':''#) (#=obj.collapsed?'collapsed':''#)" level="(#=level#)">
