更改togglejquery顶部的文本

change text on top of toggle jquery

本文关键字：文本顶部 togglejquery 更改更新时间：2023-09-26

我有一堆这样的，当用户单击"最大化"时，div会展开以显示内容。内容向下切换后，底部要最小化的链接可见。当单击该链接时，它将正确切换，我只是在寻找一种方法来更改第一个链接中的文本，因为目前jQuery只更改单击的链接的文本。有什么方法可以轻松做到这一点吗？使用Parent()然后使用Child()返回到顶部表a？

切换时，应将both#bridge分别更改为+ Expand或- Minimize。

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>

不要使用#some-id href来切换元素，而是放在可重用的var中，这是所有按钮的公共父级。

jsBin演示

将类.slide_content添加到所有可滑动元素（.faqcontainer）（或者只使用.faqcontainer而不是上面提到的，我不确定它是否是一个普通类）
完成后，我们必须找到父元素的共同点：-按钮和-一个使用.closest()的可滑动内容。。。太棒了你有一个！是<div class='bdrroundfg'>
让我们在一个变量中使用他：var common_parent = $(this).closest('.bdrroundfg');

现在我们只需要让jQ检索那个元素——他的孩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

点击时，我们需要切换我们的第一个（.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

您的代码应该是这样的：

 $(".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...
     });
 
 });

试试这个：

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