JQuery Ajax執行過程AOP攔截

JQuery Ajax過程AOP：用於在Ajax請求發送過程當中執行必備操做，好比加載數據訪問令牌。

$.ajaxSetup({
	type: "POST",
	error: function(jqXHR, textStatus, errorThrown){
		switch (jqXHR.status) {
			case(500):
				alert("服務器系統內部錯誤");
				break;
			case(401):
				alert("未登陸");
				break;
			case(403):
				alert("無權限執行此操做");
				break;
			case(408):
				alert("請求超時");
				break;
			default:
				alert("未知錯誤");
		}
	}, 
	success: function(data) {
	},
	statusCode:{
		200 : function() {
			
		}
	},
	beforeSend: function(jqXHR) {
		var ex_cnn = getCookie("ex_cnn");
		var ex_cnv = getCookie("ex_cvn");
		if(ex_cnn == null || ex_cnn == "" || ex_cnv == null || ex_cnv == ""){

		}
		var ex_cvn = getCookie(ex_cnn);
		var ex_cvv = getCookie(ex_cnv);
		jqXHR.setRequestHeader("platform", ex_cvn);
		jqXHR.setRequestHeader("mstoken", ex_cvv);
			
		var msinit_validtype = getCookie("msinit_validtype");
		var msinit_validvalue = "";
		if(msinit_validtype == "oa"){
			msinit_validvalue = getCookie("oa_token");
		} else if(msinit_validtype == "fp"){
			msinit_validvalue = getCookie("sfut");
		}
			
		jqXHR.setRequestHeader("validatetype", msinit_validtype);
		jqXHR.setRequestHeader("validatevalue", msinit_validvalue);
	}
});
