Ext JS 4：JavaScript异常“TypeError：Ext.resetElement未定义”在Ext JS 4.1.1版中 [英] Ext JS 4: JavaScript Exception "TypeError: Ext.resetElement is undefined" in Ext JS version 4.1.1

问题描述

Ext JS 4.1.1打破了我使用ASP.NET设置的代理。我不得不切换到版本4.1.0来解决问题。只是想我会抛出这个问题，直到被Sencha解决。

JavaScript异常：

TypeError：Ext.resetElement is undefined= =>... s.styleProxyEl ||（Ext.AbstractComponent.prototype.styleProxyEl==> ext-all-debug.js（第26960行）

< img src =https://i.stack.imgur.com/G5ukg.jpgalt =enter image description here>

  getStyleProxy：function（cls）{
 
 var result = this.styleProxyEl ||（Ext.AbstractComponent.prototype.styleProxyEl = Ext.resetElement.createChild（{
 style：{
 position：'absolute'，
 top：'-10000px'
} 
}，null，true））; 
 
 result.className = cls; 
返回结果; 
}，
  

解决方法：

下载ExtJS框架的4.1.0版本，而不是使用4.1.1版。

如果有人可以解释这里发生了什么，我会把他们的答案标记为正确。这是我正在使用的代理。

  Ext.define（'Ext.ux.AspWebAjaxProxy'，{
扩展：'Ext.data.proxy.Ajax'，
 require：'Ext.data'，
 
 buildRequest：function（operation）{
 var params = Ext.applyIf operation.params || {}，this.extraParams || {}），
请求; 
 params = Ext.applyIf（params，this.getParams（params，operation））; 
 if （operation.id&！params.id）{
 params.id = operation.id; 
} 
 
 params = Ext.JSON.encode（params）; 
 
 request = Ext.create（'Ext.data.Request'，{
 params：params，
 action：operation.action，
 records：operation.records ，
 operation：operation，
 url：operation.url 
}）; 
 request.url = this.buildUrl（request）; 
 operation.request = request; 
返回请求; 
} 
}）; 
  

解决方案

确保您使用 Ext.onReady（function（）{...}）。 ExtJS使用 onReady 呼叫之前设置的 Ext.resetElement 。

Ext JS 4.1.1 broke my proxies I had set up with ASP.NET. I had to switch back to version 4.1.0 to resolve the issue. Just thought I'd throw this issue out there until it's resolved by Sencha.

JavaScript Exception:

"TypeError: Ext.resetElement is undefined" ==> "...s.styleProxyEl || (Ext.AbstractComponent.prototype.styleProxyEl" ==> ext-all-debug.js (line 26960)

getStyleProxy: function(cls) {

    var result = this.styleProxyEl || (Ext.AbstractComponent.prototype.styleProxyEl = Ext.resetElement.createChild({
        style: {
            position: 'absolute',
            top: '-10000px'
        }
    }, null, true));

    result.className = cls;
    return result;
}, 

Workaround:

Download version 4.1.0 of the ExtJS framework instead of using version 4.1.1.

If someone can explain what broke here exactly, I'll mark their answer as correct. Here is the proxy I'm using.

Ext.define('Ext.ux.AspWebAjaxProxy', {
    extend: 'Ext.data.proxy.Ajax',
    require: 'Ext.data',

    buildRequest: function (operation) {
        var params = Ext.applyIf(operation.params || {}, this.extraParams || {}),
                                request;
        params = Ext.applyIf(params, this.getParams(params, operation));
        if (operation.id && !params.id) {
            params.id = operation.id;
        }

        params = Ext.JSON.encode(params);

        request = Ext.create('Ext.data.Request', {
            params: params,
            action: operation.action,
            records: operation.records,
            operation: operation,
            url: operation.url
        });
        request.url = this.buildUrl(request);
        operation.request = request;
        return request;
    }
});

解决方案

Make sure you are using Ext.onReady(function() { ... }). ExtJS uses Ext.resetElement which is set before onReady call.
