Question

在附加元素占据相同的Y位置后，

按钮不起作用，为什么会发生这种情况？我接受了其他帖子的建议，并以某种方式使我的onclick功能，但我仍然有问题

JS：

 var welldataArray = [];
 var productiondataArray = [];
 var radioSearchPartB = 0;
 var productionjsonarray = [];



$(document).ready(function() {

    $(document).on('click', '.clearButton', function (){
    $('#result1').empty();
    $('#block1').val("");
    $('#block2').val("");
    $('#block3').val("");
    $('#block4').val("");
    $('#block5').val("");
});

$(document).on('click', '.searchButton', function(){
    //validate
    if(radioSearchPartB == 1){
        var block1 = $("#block1").val().toUpperCase();
        var firstcharBlock1 = block1.substring(0,1);

Answer 1

好吧，如果您从正文中移除onload="loadPartB()"并调用文档中的loadPartB();，您的按钮就会生效。（）

$(document).ready(function() {
 loadPartB();
 $(document).on('click', '.clearButton', function (){
 $('#result1').empty();
 $('#block1').val("");
 $('#block2').val("");
 $('#block3').val("");
 $('#block4').val("");
 $('#block5').val("");
});

Answer 2

您可以将delegate()用作：

$(document).delegate('click', '.clearButton', function (){
     // your code
});

文件：http://api.jquery.com/delegate/

此事件总是设置为新元素

按钮后，按钮不起作用 - jquery
