jQuery.ajax({
url: path,
type: "POST",
dataType:'json',
data:{word : 'a'},
success:function(json) {
var isSuccess = json.isSuccess;
//alert(json.content.length);
},
error:function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status); // 200
extStatus); // parsererror
alert(errorThrown); // SyntaxError: Unexpected end of input
}
