如何获得点击哪个按钮？

Question

我想检查一个特定的按钮被点击时的情况如何做到这一点？

$(document).ready(function() { 
     var prm = Sys.WebForms.PageRequestManager.getInstance(); 
     prm.add_initializeRequest(InitializeRequest); 
     prm.add_endRequest(EndRequest); 
     Search("Other"); 


    }); 

    function InitializeRequest(sender, args) { 
    } 

    function EndRequest(sender, args) { 
     alert(sender._postBackSettings.sourceElement.id) 
     var str1 = new String(sender._postBackSettings.sourceElement.id); 
     if (sender._postBackSettings.sourceElement.id == ContentPlaceHolder1_btnNew) { 
      alert("You have clicked new") 
      Search("NEW"); 
     } 

     else { 
     alert("OTHERS") 
      Search("Other"); 
      } 


    }

我得到了解决办法，将其分配给一个字符串值并检查条件是否为字符串。

$(document).ready(function() { 
     var prm = Sys.WebForms.PageRequestManager.getInstance(); 
     prm.add_initializeRequest(InitializeRequest); 
     prm.add_endRequest(EndRequest); 
     Search("Other"); 


    }); 

    function InitializeRequest(sender, args) { 

    } 

    function EndRequest(sender, args) { 

     var str1 = new String(sender._postBackSettings.sourceElement.id); 

     if (str1 == "ContentPlaceHolder1_btnNew") {     
      alert("You have clicked new") 
     } 

     else { 
      alert("You have clicked others") 
     } 

    }

试试这个代码：

$(document).ready(function() { 

    $("#btnSubmit").click(function(){ 
     // Call here that function which you want to call 
    }); 
});

如果你有充足的按钮，给他们一个相同的类名。例如：class =“myButton” 有关特定按钮的信息可以保存在其属性中。例如：OBJECTID =“12345”，那么你的代码可以来如下：

$(".myButton").click(function(){ 
     console.log($(this)); // this gives you the DOM Object of the button which is clicked 
     // now to get the attribute of the button i.e objectId you can do this 
     $(this).attr("objectId"); 
     /* Depending on this you can handle your condition */ 
    }); 

如果正在动态创建你的按钮，你可以使用这个

$(".myButton").live('click', function(){ 
      console.log($(this)); // this gives you the DOM Object of the button which is clicked 
      // now to get the attribute of the button i.e objectId you can do this 
      $(this).attr("objectId"); 
      /* Depending on this you can handle your condition */ 
     }); 

现场已被弃用的版本上面jQuery的1.7。 2。

您可以使用“on”代替它。
