how to call jQuery(this) from anchor tag onclick function

Question

I have

 

            
New Test
            &         


        

Answer 1

You need to send the element through the function like this

HTML

onclick="setSelectedTestPlan(this);"

js

function setSelectedTestPlan(ele) {      
       jQuery("#tree ul li").each(function () {
            jQuery(this).removeClass("selected");
        });

        jQuery(ele).closest('li').addClass("selected");
    }

Answer 2

One line:

jQuery(this).closest('li').addClass("selected").siblings().removeClass("selected");

but you will have to amend your event to pass through 'this';

onclick="setSelectedTestPlan(this);"

Answer 3

HTML

<li><a onclick="setSelectedTestPlan(this);" href="javascript:void(0);">New Test</a></li>

js

function setSelectedTestPlan(el) {      
       jQuery("#tree ul li").removeClass("selected");
       jQuery(el).closest('li').addClass("selected");
    }

or

js

function setSelectedTestPlan(el) { 
   jQuery(el).closest('li').addClass("selected").siblings().removeClass("selected");
}

Answer 4

HTML

<li><a onclick="setSelectedTestPlan.call(this, event);" href="javascript:void(0);">New Test</a></li>

JS

function setSelectedTestPlan(e) {
   jQuery(this)closest('li').addClass("selected").siblings().removeClass("selected");
}

Answer 5

function setSelectedTestPlan(e) {
    jQuery("#tree ul li").each(function () {
        jQuery(this).removeClass("selected");
    });

    jQuery(e).closest('li').addClass("selected");
}

 <li><a onclick="setSelectedTestPlan(this);" href="javascript:void(0);">New Test</a></li>

alternative

    <ul>
        <li><a class="mylink" href="javascript:void(0);">New Test</a></li>
        <li><a class="mylink" href="javascript:void(0);">New Test fdgfdgfdgfdgfdgfdgfdgfdg fdg</a></li>
        <li><a class="mylink" href="javascript:void(0);">New Plan</a></li>
        <li><a class="mylink" href="javascript:void(0);">Test</a></li>
    </ul


$(function(){
$(".mylink").click(function(e){
     $(".mylink").parents("li").removeClass("selected");
     $(this).parents("li").addClass("selected");
     e.preventDefault();   
   });
 });
