未捕获的TypeError:无法读取未定义的属性'ajax' [英] Uncaught TypeError: Cannot read property 'ajax' of undefined

问题描述

我尝试通过POST调用使用AJAX从表中删除项目.

I tried deleting an item from a table with AJAX via a POST call.

///// DELETE INDIVIDUAL ROW IN A TABLE /////
jQuery('.stdtable .delete').live('click', function (e) {
//var newsId1 = $(this).attr("title");

e.preventDefault();

var p = jQuery(this).parents('tr');

if (p.next().hasClass('togglerow'))
   p.next().remove();

p.fadeOut(function () {
    jQuery(this).remove();
});

$.ajax({
  URL: "/AdminPanel/News/DeleteNews",
  data: { "newsId": 1 },
  dataType: "json",
  type: "POST",
  success: function (msg) {
  alert(msg);
}
}); 

在这段代码中，我得到 Uncaught TypeError:无法读取未定义的属性'ajax'.

In this code I get Uncaught TypeError: Cannot read property 'ajax' of undefined.

推荐答案

您尝试使用jQuery

jQuery.ajax({
  URL: "/AdminPanel/News/DeleteNews",
  data: { "newsId": 1 },
  dataType: "json",
  type: "POST",
  success: function (msg) {
  alert(msg);
}

您可以将代码包装在DOM ready函数中，该函数在函数范围内在本地设置$的值，这样您就可以始终使用$

You can wrap your code in a DOM ready function that sets the value of $ locally in the function scope, that way you can always use $

jQuery(function($) {
    // code goes here
});
