jQuery使用加号和减号图标隐藏和显示切换div

Question

我有代码为节目工作并隐藏div.当show和hide处于活动状态时,如何将两个不同的图标添加为精灵图像？

例如:+图标用于显示我,然后用-图标用于隐藏我.

这是代码,我有:http: //jsfiddle.net/BLkpG/

$(document).ready(function(){
   $(".slidingDiv").hide();
   $(".show_hide").show();

    $('.show_hide').click(function(){
    $(".slidingDiv").slideToggle();
  });
});

切换到+或-时需要将图像更改为上面的内容.

谢谢

Answer 1

尝试这样的事情

jQuery的

$('#toggle_icon').toggle(function() {

    $('#toggle_icon').text('-');
    $('#toggle_text').slideToggle();

}, function() {

    $('#toggle_icon').text('+');
    $('#toggle_text').slideToggle();

});

HTML

<a href="#" id="toggle_icon">+</a>

<div id="toggle_text" style="display: none">
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s
</div>

CSS

$('#toggle_icon').toggle(function() {

    $('#toggle_icon').text('-');
    $('#toggle_text').slideToggle();

}, function() {

    $('#toggle_icon').text('+');
    $('#toggle_text').slideToggle();

});

我会说最优雅的方式是:

<div class="toggle"></div>
<div class="content">...</div>

那么css:

.toggle{
 display:inline-block;
height:48px;
width:48px;  background:url("http://icons.iconarchive.com/icons/pixelmixer/basic/48/plus-icon.png");
}
.toggle.expanded{
  background:url("http://cdn2.iconfinder.com/data/icons/onebit/PNG/onebit_32.png");
}

和js:

$(document).ready(function(){
  var $content = $(".content").hide();
  $(".toggle").on("click", function(e){
    $(this).toggleClass("expanded");
    $content.slideToggle();
  });
});

切换文本Show并Hide移动backgroundPosition Y轴

现场演示

$(function(){ // DOM READY shorthand

    $(".slidingDiv").hide();

    $('.show_hide').click(function( e ){
        // e.preventDefault(); // If you use anchors
        var SH = this.SH^=1; // "Simple toggler"
        $(this).text(SH?'Hide':'Show')
               .css({backgroundPosition:'0 '+ (SH?-18:0) +'px'})
               .next(".slidingDiv").slideToggle();
    });

});

CSS:

.show_hide{
  background:url(plusminus.png) no-repeat;
  padding-left:20px;  
}

这是 Enve 答案的快速编辑。我确实喜欢 roXor 的解决方案，但背景图像不是必需的。preventDefault每个人似乎也忘记了。

$(document).ready(function() {
  $(".slidingDiv").hide();

  $('.show_hide').click(function(e) {
    $(".slidingDiv").slideToggle("fast");
    var val = $(this).text() == "-" ? "+" : "-";
    $(this).hide().text(val).fadeIn("fast");
    e.preventDefault();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" class="show_hide">+</a>

<div class="slidingDiv">
