Stackoverflow代码段-使用javascript onclick function 删除当前行工作正常。

function removeRow(onclickTAG) {
    // Iterate till we find TR tag. 
    while ( (onclickTAG = onclickTAG.parentElement)  && onclickTAG.tagName != 'TR' );
            onclickTAG.parentElement.removeChild(onclickTAG);
}

jsfiddle - test 和平面html文件的代码不工作,至少与javascript。

无法删除|调用删除行函数。删除行时,从 Added Total .
我应该只允许输入标记使用number,但它仅适用于第一行输入元素。 Input type must be text only. type number allows these like {.+-}

您的代码有两个问题:

$('table#productTable:.remove-row').on('click', function () {

:. 是一个语法错误,它显示在控制台中。

其次,要在动态html上放置事件侦听器,您必须使用 $(document).on() 例如:

$(document).on('click', '.remove-row', function(){

on 在动态添加元素时,单击事件处理程序。

已更新两个事件: 1、删除按钮事件

$('table#productTable').on('click', '.remove-row', function() {
  //$("#productTable").each(function () {
  // added total minus deleting element price.
  $(this).closest('tr').remove(); // https://stackoverflow.com/a/11553788/5081877
  //$(element).parent().remove();
  //});
});

$('table#productTable').on('input propertychange',' > tbody > tr > td:nth-child(3) > input', function() {
  $.each($('input[type=text]'), function() {
    this.value = this.value.replace(/[^0-9]/g, '');
  });
});

参考此 fiddle

请换衣服 $('.row).onclick 这样地

$('table#productTable').on('click', '.remove-row', function()

$("#productTable").each(function () {
