未捕获的TypeError:elem.nodeName.toLowerCase不是函数Jquery [英] Uncaught TypeError: elem.nodeName.toLowerCase is not a function Jquery

问题描述

我正在做一个工作正常的项目，但是今天突然出现了TypeError

i am working on a project which was working fine but suddenly today it is showing an TypeError

未捕获的TypeError:elem.nodeName.toLowerCase不是函数Jquery

Uncaught TypeError: elem.nodeName.toLowerCase is not a function Jquery

下面是我得到错误的代码

below is my code where i got the error

// A method for determining if a DOM node can handle the data expando
acceptData: function( elem ) {
    // Do not set data on non-element because it will not be cleared (#8335).
    if ( elem.nodeType && elem.nodeType !== 1 && elem.nodeType !== 9 ) {
        return false;
    }

    var noData = elem.nodeName && jQuery.noData[ elem.nodeName.toLowerCase()//**here** ];

我稍稍更改了代码，并在toLowerCase之前将其添加到String，但仍然遇到相同的错误，

I changed my code a bit and added toStringbefore toLowerCase but still getting the same error,

像这样改变

changed Like this

var noData = elem.nodeName && jQuery.noData[ elem.nodeName.toString().toLowerCase()//**like this** ];

这里可能出什么问题?

推荐答案

基于Nakama Hiroshi的回答. 我发现了错误.在输入中添加了名称"nodeName".

Base on Nakama Hiroshi's answer. I found my mistake.I add name "nodeName" for the input.

<input type="text" id="nodeName"  name="nodeName"  />

"nodeName"是jQuery的保留名称

"nodeName" is reserved name by jQuery

然后将"nodeName"更改为其他名称.然后解决问题

And I change "nodeName" to other name. Then fix the problem
