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

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,

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"  />

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
