尝试这样的事情：
<div id="LoadingImage" > <img src="" /></div><script> function ajaxCall(){ $("#LoadingImage").show(); $.ajax({ type: "GET", url: surl, dataType: "jsonp", cache : false, jsonp : "onJSONPLoad", jsonpCallback: "newarticlescallback", crossDomain: "true", success: function(response) {$("#LoadingImage").hide(); alert("Success"); }, error: function (xhr, status) { $("#LoadingImage").hide(); alert('Unknown error ' + status); } }); }</script>
