目前我的工作我的第一次的jQuery / AJAX调用和我在遇到如何将服务器端的结果填充到我的列表框的问题。弹簧控制器返回我的数据正确(希望)我只是有jQuery的部分与填充列表框的问题。
Currently I am working on my first jquery/ajax call and I'm having issues with how to populate the server side results into my listbox. The spring controller returns me the data correctly (hopefully) i just have issues with the jquery part with filling the listbox.
这是我的ajax调用
$(function() {
$projectKey = $('#projectKey');
$projectKey.change (
function() {
$.ajax({
type: "GET",
url: "getVersionsByProjectKey",
data: {"projectKey": $projectKey.val() },
dataType: 'json',
success: function(data){
alert('success');
alert(data);
$('#jiraVersion').append(
$('<option></option>').html(data)
);
}
});
}
);
});
这是我的控制器是这样的:
@RequestMapping(value="/getVersionsByProjectKey", method = RequestMethod.GET)
public @ResponseBody List<String> getVersionsByProjectKey(@RequestParam(value = "projectKey") String projectKey) {
List<String> versions = new ArrayList<String>();
versions.add("Chuck");
versions.add("Norris");
versions.add("John");
versions.add("Doe");
return versions;
}
这是我要填写数据的列表框:
This is the listbox that I want to fill the data in:
<td>
<form:select path="jiraVersion" id="jiraVersion">
</form:select>
</td>
正如我以前说过,我只是我自己熟悉的jQuery的现在,并试图一对夫妇从谷歌,但没有喜悦的解决方案。我想:
As I said before, I am just familiarizing myself with the jquery now and tried a couple of solutions from google but no joy. I tried:
success: function(data){
alert('success');
alert(data);
$.each(data, function(index, item) {
$("#jiraVersion").get(0).options[$("#jiraVersion").get(0).options.length] =
new Option(item.Display, item.Value);
});}
等等等等
警报('成功')写信给我:查,诺里斯,约翰,李四
。
The alert('success') writes me: Chuck,Norris,John,Doe
.
如果我直接发送请求 / getVersionsByProjectKey?projectKey = AIL
我找回了 [查克,诺里斯,约翰,李四]
和我也尝试修改成功
有:
success: function(data){
alert('success');
alert(data);
$('#jiraVersion').append(
$('<option></option>').html(data)
);
}
然后我的列表框只包含一个选项,这是的 ChuckNorrisJohnDoe 的。知不知道我做错了什么?
Then my listbox contains just one option which is ChuckNorrisJohnDoe . Any idea what I am doing wrong?
随着数据
从Ajax调用是数组 [查克 ,诺里斯,约翰,李四]
,你需要遍历它使用的 jQuery.each()
:
As the data
from the Ajax call is the array ["Chuck","Norris","John","Doe"]
, you need to iterate through it using jQuery.each()
:
使用此功能为成功
:
success: function(data){
$.each(data, function(index, value) {
$('#jiraVersion').append($('<option>').text(value).val(index));
});
}
这将追加/生成:
<form:select path="jiraVersion" id="jiraVersion">
<option value="0">Chuck</option>
<option value="1">Norris</option>
<option value="2">John</option>
<option value="3">Doe</option>
</form:select>
