How to set the JSTL variable value through javascript variable
提问by Dinesh Maske
I would like to display htmlcode when the user clicks on a particular box.
我想在用户单击特定框时显示html代码。
When the user selects a value from one of the available options, a JavaScript function is invoked which stores the selected value against a variable.
当用户从可用选项之一中选择一个值时，将调用一个 JavaScript 函数，该函数将所选值存储在一个变量中。
I am having difficulty with implementing code to compare the value of ELvariable with the innerHTMLvariable.
我在实现代码以将EL变量的值与innerHTML变量进行比较时遇到困难。
Below is the code I am currently using:
以下是我目前使用的代码：
var groupid = parseInt($('#selectgroup').val());
document.getElementById("facilityTable").innerHTML= "<c:forEach var='group'
items='${groups}'>"+
"<c:if test='${group.key == (groupid)}'>"+
"<td>+Test+${group.value.groupName}</td>"+
"<td>${group.value.groupId}</td>" +
"</c:if>"+
"</c:forEach>";

Your JSTLtags will not be a part of JSoutput, so there is not reason to put them into quotes, e.g.:
你的JSTL标签不会是JS输出的一部分，所以没有理由把它们放在引号中，例如：
document.getElementById("facilityTable").innerHTML= ""
<c:forEach var='group' items='${groups}'>
<c:if test='${group.key == (groupid)}'>
+ "<td>+Test+${group.value.groupName}</td>"+
"<td>${group.value.groupId}</td>"
</c:if>
</c:forEach>;
