jQuery的JavaScript显示/隐藏切换问题

Question

I have two issues. 1. I want to remove phase content from java so that I will only have StepsContent in it as I want expand all the steps. 2. when i click Step 1 first, and then click expand all, Step 1 collapses and expand all text issues. Any workaround. Also if there is an easier way to do this through Css please let me know.

JSFIDDLE http://jsfiddle.net/Y3GYR/1/

or below is the code:

   jQuery(".phaseContent").hide();
jQuery(".stepsContent").hide();
//toggle the componenet with phase level
jQuery(".phaseHeading .heading1").click(function () {
    $(this).toggleClass("active");
    var th = jQuery(this).parent();
    jQuery(th).next(".phaseContent").slideToggle(500);
    return false;
});
jQuery(".stepsHeading .heading1").click(function () {
    $(this).toggleClass("active");
    var th = jQuery(this).parent();
    jQuery(th).next(".stepsContent").slideToggle(500);
    return false;
});

//Expand and collapse toggle

$(".accordion-expand-all").click(function () {
    var expandLink = $(this);
    var contentAreas = $(expandLink).closest(".phaseContent").find(".stepsContent");

    // Toggle the content area visibility
    $(contentAreas).toggle();

    // If the content area is now visible
    if ($(contentAreas).is(':visible')) {
        // Change it to the collapse text
        $(expandLink).text('Collapse - all steps');
    } else {
        // Change it to the expand text
        $(expandLink).text('Expand - all steps');
    }

    $(expandLink).closest(".phaseContent").find(".stepsHeading .heading1").toggleClass("active");

    return false;
});

To right collapse\\expand you need to manually select what to do, if you toggle array of elements

$(expandLink).closest(".phaseContent").find(".stepsContent")

it will toggle visibility of each of them. Just add a var, and put in it you current show\\hide position like that:

    var collapsed = 1;
$(".accordion-expand-all").click(function () {
    ...
        if (collapsed == 0)
     {
        $(contentAreas).hide("slide");
        $(expandLink).text('Expand - all steps');
        collapsed =1;
    }
    else
    {
        $(contentAreas).show("slide");
        $(expandLink).text('Collapse - all steps');
        collapsed = 0;
    }
})
