问题描述

如何在Extjs4中添加beforerequest和requestcomplete事件到特定的ajax请求？

how to add beforerequest and requestcomplete event to specific ajax request in Extjs4?

注意

推荐答案

Ext.Ajax.on("beforerequest", function(){
        console.info("beforerequest");
    });
Ext.Ajax.on("requestcomplete", function(){
        console.info("requestcomplete");
    });

Ext.Ajax.request({
    url: 'get-nodes.php',
    success: function(response){
        var text = response.responseText;
        console.info("response");
    }
});

或者在特定情况下需要它，请尝试：

or if you need it in specific cases, try this :

Ext.define('myAjax', {
    extend: 'Ext.data.Connection',
    singleton: true,
    constructor : function(config){
        this.callParent([config]);
        this.on("beforerequest", function(){
            console.info("beforerequest");
        });
        this.on("requestcomplete", function(){
            console.info("requestcomplete");
        });
    }
});

myAjax.request({
    url: 'get-nodes.php',
    success: function(response){
        console.info("response");
    }
});
