Question

我有很多这些，当用户点击最大化时，div会展开以显示内容。内容切换后，可以看到底部最小化的链接。单击该链接时，它将正确切换，我只是想找到一种方法来更改第一个链接中的文本，因为当前jQuery只更改了单击链接的文本。有没有办法轻松做到这一点？使用Parent()然后使用Child()返回顶部a的内容？

切换时，应将 #bridge分别改为+ Expand或- Minimize。

的javascript

<script type="text/JavaScript" language="javascript">
    $(document).ready(function() {
        $(".expand").click(function(e) {
            e.preventDefault();
            var toggle = $(this).attr('href');

            var txt = $(this).text() == '+ Expand' ? '- Minimize' : '+ Expand';
            $(this).text(txt);
            $(toggle).slideToggle('fast', function() {                

            });

        });
    });
</script>

Answer 1

请勿使用#some-id href切换元素，而应使用可重复使用的var 全部按钮的公共父级。

jsBin demo

为所有可滑动元素（.slide_content）添加一个班级.faqcontainer（或者只使用.faqcontainer代替上述提法，我不确定它是否为普通班级）
完成我们必须找到父元素的常见内容： - 使用.closest()两个按钮和-one可滚动内容...太棒了！你有一个！这是<div class='bdrroundfg'> !!!
我们在var：var common_parent = $(this).closest('.bdrroundfg');

现在我们只需要为该元素进行jQ检索 - 他的子按钮和他的可滑动内容：

    var slide_content = common_parent.find('.slide_content'); // the added class!
    var all_buttons   = common_parent.find('a.expand');       // both buttons

点击后我们需要切换第一个（.eq(0)）按钮的文本

     var txt = $(this).text() === '+ Expand' ? '- Minimize' : '+ Expand';
     all_buttons.eq(0).text(txt); // target only the first one in the collection

您的代码应如下所示：

 $(".expand").click(function(e) {
     e.preventDefault();
     var common_parent = $(this).closest('.bdrroundfg');
     var slide_content = common_parent.find('.slide_content'); // the added class!
     var all_buttons   = common_parent.find('a.expand');   

     var txt = $(this).text() === '+ Expand' ? '- Minimize' : '+ Expand';
     all_buttons.eq(0).text(txt);    // toggle text - first button only!     

     $(slide_content).slideToggle('fast', function(){
          // do something here...
     });

 });

Answer 2

试试这个：

 if (this.id == 'A2') {
     $('#expand').text("+ Expand")
 }
