15-ajax的data传参的两种方式以及乱码的解决

/**
 * 订单取消
 * @return {Boolean} 处理是否成功
 */
function orderCancel(orderId,commant){
	var flag = false;
	$.ajax({
	    type: "POST",url: "../order/orderCancel.action",//orderModifyStatus
	   <span style="color:#ff0000;"><strong>①</strong></span><strong><span style="color:#ff0000;"> data: {"orderId":orderId,"commant":commant},</span></strong>
	    dataType:"json",async:false,cache:false,success: function(data){
	    	var member = eval("("+data+")"); //包数据解析为json 格式                                                          
	        if(member.success=="true"){
        		flag = true;
	        }else if(member.success=="false") {
	        	alert(member.info);
	        }
		},error: function(json){
			alert("订单取消异常，请刷新后重试...");
		}
    });
    hidediv();
    return flag;
}

② data: "orderId=" + orderId + "&commant=" + commant

乱码解决：

发生情况，项目的编码方式为gbk,页面的编码是gbk,使用ajax进行传值的过程中出现了乱码，解决的步骤如下，供参考。

页面获取值

var url="addPatternInfo.action";
var params={
	"patternInfo.Area_name":<strong><span style="color:#ff0000;">encodeURI(area_name)</span></strong>,"patternInfo.name1":encodeURI(name1)
};
$.ajax({
	async:false,type:"post",url:url,data:params,dataType:"json",<span style="color:#ff0000;"><strong>contentType:'application/x-www-form-unlencoded;charset=UTF-8',</strong></span>
	cache:false,success:function(data){
		alert("OK");
 	}
});

patternInfo.setName1(URLDecoder.decode(patternInfo.getName1(),"UTF-8"));
