页面重新加载jQuery后如何显示div和当前链接处于活动状态

Question

I want to show a div and a link active which is clicked after page reload. Initially class active is called to first link and div is hidden.

I checked everything I could think of, but didn't get the solution as my code is not working after page reload.

Please see the html and jquery code:

<div class="sub-cols" style="display:none;">
    <div class="wraper-berkowits">
    <a class="active" href="<?php echo Mage::getBaseUrl() ?>products-for-sale/attachments.html">Attachments</a>
    <a href="<?php echo Mage::getBaseUrl() ?>products-for-sale/removal.html">Removal</a></li>
    <a href="<?php echo Mage::getBaseUrl() ?>products-for-sale/hair-loss-store.html">Hair Loss</a></li>
    <a href="<?php echo Mage::getBaseUrl() ?>products-for-sale/care-maintenance.html">Care &amp; maintenance </a>
    </div>
</div>


jQuery(document).ready(function() {
    jQuery('.menu:first-child').addClass('first'); 

    jQuery('li.last a').click(function() {  
        jQuery('.sub-cols').show();
        return false;
    }); 

    jQuery(".sub-cols a").click(function () {        
        jQuery(this).addClass('active').siblings().removeClass('active'); 

    });
});

Please check the above code and advise me how to get the desired result.

As from your comments the question is better understood now As your need is to regain the state of the link even after the page reload. I can provide you the hint of achieving it

There are two ways - 1) you can $_SESSION in php to store the link clicked and can have it display using jquery

2) Using javascript only - use window.localStorage – stores data with no expiration date

When you need to set a variable that should be reflected in the next page(s), use:

var someVarName = "value";
localStorage.setItem("someVarName", someVarName);

In your code you can do something like this

jQuery(".sub-cols a").click(function () {
        localStorage.setItem("someVarName", jQuery(this).text());
        jQuery(this).addClass('active').siblings().removeClass('active');
    });
    jQuery(".sub-cols").show();

And in any page (like when the page has loaded), get it like:

var someVarName = localStorage.getItem("someVarName");

.getItem() will return null or the value stored.

for your example you can use like this

if(localStorage.getItem("someVarName")!=null){
        $('a').filter(function(){
                return this.innerHTML == localStorage.getItem("someVarName"); 
            }).css({background:"#F00"});
    }

I have provided an updated demo - http://jsfiddle.net/bvqnzuwa/3/ To test it click on any link and then reload the page. You will see a background color on the link you clicked even after page reload.
