我有一个与某个值的宽度, 这个值正在同步更新 。 所以, 我希望 jquery 听一个值, 如果它等于, 换句话说“ 测试 ” 我想隐藏另一个 html 元素 。 我无法确定我应该使用什么事件, 因为 < href=" http:// api. jquery. com/ change/ " rel=" nofollow >. change 只对文本框和选择有效 。 change 只对文本框和选择有效 。

问题回答

您能否访问快速更新值的方法的回调功能? 如果可以, 您可以在其中丢下一个分析响应的有条件/ 听力器。 类似 :

$.ajax({
   success: function(responseData) {
      if(responseData.specificKeyValue ==  test ) {
          $( element to hide ).hide();
      }
   }
});

我会在下面做一些事情。这基本上会触发一个自定义事件,当你更新时。

<强度 > 注 :以下为演示代码,试图了解想法并相应执行。

$(function() {
    var $result = $( #result );
    setInterval(function() {
       $result.append( Span Updated ).trigger( spanChange );
    }, 1000);

    $result.on( spanChange , function () {
        //your custom span change listener
        console.log( Span got updated );
    });
});
