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");
}
});

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