如何在Extjs4中将beforerequest和requestcomplete事件添加到特定的ajax请求？
问候
解决方法
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");
}
});
或者如果您在特定情况下需要它,请尝试以下方法：
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");
}
});
