如何使用JQuery遍历从Web服务返回的字符串列表 [英] How to iterate through a list of strings returned from a web service using JQuery
问题描述
这是我的第一个JQuery经历,而且我的期限很紧.这是一个令人尴尬的问题,但这是可行的.我正在调用一个返回字符串列表的Web服务(可以正常工作并返回OK).代码在下面
This is my first JQuery experience and I'm on quite a tight deadline. It's a bit of an embarrassing question, but here goes. I'm calling a web service that returns a list of strings (which works and returns OK). Code is below
$(document).ready(
function()
{
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CatList.asmx/GetCatergoies",
data: "{}",
dataType: "json",
success: onActionCompleted
});
}
)
function onActionCompleted(data) {
var resultData = data['d'];
alert(resultData);
}
警报会产生一个逗号分隔的字符串,表示来自Web服务的结果.我无法弄清我的一生如何遍历结果.当我做这样的事情时:
The alert produces a comma seperate string of the results from the web service. I can't figure out for the life of me how I can iterate through the results. When I do something like this:
resultData.each(
alert(this)
)
我在Firebug中遇到的只是这个错误:
All I get in Firebug is this error:
resultData.each is not a function
任何指针吗?
推荐答案
谢谢!没有反馈,我将无法解决.我仍然不完全确定resultData是什么格式.我在代码上做了一些复制和粘贴,所以不确定什么数据['d']将列表转换成json术语.
Thanks! I wouldn't have been able to solve it without the feedback. I'm still not completely sure what format resultData is. I did some copy and paste on the code so not sure what data['d'] converts the list into in json terms.
当我尝试对resultdata进行拆分时,我在Firebug中收到此错误:
When I tried the split on resultdata I got this error in Firebug:
resultData.split不是函数
resultData.split is not a function
最后,我只对结果数据使用了$ .each(),但没有拆分,它可以正常工作.
In the end I just used the $.each() on resultdata without the split and it worked.
function onActionCompleted(data) {
var resultData = data['d'];
$.each(resultData, function() {
alert(this)
})
}
