jquery ajax

$.ajax({
type: 'POST',
dataType:"json",
url: "https://localhost:44343/api/Values/getTel",
data:{
"tel":"13714390531"
},function(result) {
alert("返回值：" + result);
}
});

 

同步模式 async:false,（默认为异步）

 

成功案例

//判断宠物存不存在未结算的保障卡服务预售，如果存在，不让提交
var IsExist = "false";
$.ajax({
type: "GET",
url: "/AdvanceSale/IsExistAdvanceSale",
dataType: "json",
async: false,
data: {
"caseNum": CaseInfo.CaseNum,
},
success: function (result) {
IsExist = result.toString();
}
});

if (IsExist == "true") {
layer.msg("存在未结算的保障卡服务预售订单");
return;
}

 

 

同步的另一种写法

function submitMsg() {
var jsonData = $("form").serialize();
if (!validateForm()) {
return false;
}

if (true) {
var isExist = 0;
$.ajaxSettings.async = false;
$.ajax({
type: "post",
url: "@Url.Content("~/OutPatient/IsExistMember")",
data: { tel: $('#TEL').val(), id: $("#Id").val() },
async: false,
success: function (data) {
if (data != '') {
layer.msg('@HIS.MyResurces.GlobalResource.lbl_This_Mobile_already_exist');
isExist = 1;
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
// 状态码
console.log(XMLHttpRequest.status);
// 状态
console.log(XMLHttpRequest.readyState);
// 错误信息
console.log(textStatus);
}
});
$.ajaxSettings.async = true;

if (isExist == 1) {
return false;
}
}
