推荐答案

(" ).click(函数(e){ e.preventDefault(); sendData3(); }); 函数sendData3(){

("#Button3").click(function (e) { e.preventDefault(); sendData3(); }); function sendData3() {

.support.cors = true ;

.support.cors = true;

.ajax ({ 类型:" ， url:" ， 数据:" ， contentType:" ， dataType:" ， 成功:Success3， 错误:Error3 }); } 函数Success3(data){ // 称为此功能，但我不确定在此处写些什么来检索图像 } 函数Error3(请求，状态，错误){ alert(" );

.ajax({ type: "POST", url: "http://localhost/imageRetrieve/Service1.asmx/GetImage", data: "{ 'image_id' : 1 }", contentType: "application/json; charset=utf-8", dataType: "json", success: Success3, error: Error3 }); } function Success3(data) { // this fuction is called but i am not sure what to write here to retrieve the image } function Error3(request, status, error) { alert("error3");
