Question

我对JQuery还是陌生的，因为我一直遇到像这样的奇怪问题，没有错误，而且没有任何意义。虽然我有Google，但我无法在Google上找到它。所以，请告诉我我所缺少的。我可以在jsfiddle上完成这项工作，但其他地方都失败了。

$(document).ready(function() {
{
	var intID = null;
}

$('[delbtn]').click( function() {
	var msg = $('[delbtn]').attr("msg");
	$('#PromptDialog').html(msg);
	$('#PromptDialog').dialog( {
      title: "Delete Prompt",
      autoOpen: true,
      show: "blind",
      hide: "explode",
      modal: true,
      width: "400px",
			resizable: false,
    	buttons: [
      {
        text: "Yes",
        class: "yesClass",
        click: function () {
        	$('#resposneText').html('Yes was clicked');
          $('#PromptDialog').dialog('close');
          clearTimeout(intID);
        }
      },
      {
        text: "No",
        class: "noClass",
        click: function () {
        	$('#resposneText').html('No was clicked');
          $('#PromptDialog').dialog('close');
          clearTimeout(intID);
        }
      }],
			open: function(event, ui) {
          intID = setTimeout(function(){
              $('#PromptDialog').dialog('close');
          }, 10000);
      }
  });
});

$('#DeleteButton').click( function() {
	var msg = $('#DeleteButton').attr("msg");
	$('#PromptDialog').html(msg);
	$('#PromptDialog').dialog( {

      }],

Answer 1

您在上一条注释中提到了jQuery对话框错误，看来您的代码中没有包含jquery UI。在jQuery之后添加此代码以修复该错误：

<script
  src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"
  integrity="sha256-VazP97ZCwtekAsvgPBSUwPFKdrwD3unUfSGVYrahUqU="
  crossorigin="anonymous"></script>

Answer 2

由于您的错误涉及到一个dialog（）函数，但jQuery没有，所以您还需要在jquery之后添加jquery UI。

jQuery有时不起作用，我不确定为什么
