用户输入输入变量是表单并单击<button>
,ajax调用触发器并获取上述数据。然后根据返回的xml应该进行适当的操作。
这就是我在做的事情:
<script type="text/javascript">
...
if ($('input:text[name=ident]').val() != "")
{
$.post("<?php echo site_url('con/met/') ?>",
{doi:$('input:text[name=ident]').val()},
function(responseText){ parseXmlDoi(responseText)},
"html"
);
...
}
</script>
这是我的parseXmlDoi函数:
function parseXmlDoi(xml)
{
$('#debug').fadeIn();
$('#debug').html('');
if ($(xml).find('error').text())
{
$('#debug').html('<div dir="rtl" class=\"message warning\"><p>error</p></div>');
}
else if ($(xml).find('book').text())
{
$('#debug').html('<div dir="rtl" class=\"message info\"><p>this is a book</p></div>');
}
else if ($(xml).find('journal').text())
{
// do some stuff
}
else
{
$('#debug').html('<div dir="rtl" class=\"message error\"><p> something is wrong</p></div>');
}
}
问题:在基于上面给出的Xml的Chrome和Firefox中,它可以正常运行// do some stuff
但在IE上它显示something is wrong
表示find()
无效。< / p>
答案 0 :(得分:1)
你明确告诉jQuery将响应视为HTML而不是XML,所以你得到的是一个字符串。然后在该字符串上调用$()
,告诉它将其解析为为HTML ,而不是XML。
我看不出覆盖默认处理的任何理由,但我怀疑它可能是问题,因为IE不太像它不知道的HTML标签。
请改为尝试:
$.post(
"<?php echo site_url('con/met/') ?>",
{doi:$('input:text[name=ident]').val()},
parseXmlDoi,
"xml" // Or leave this off, your content type should trigger XML handling
);
...并将parseXmlDoi
的开头更改为:
function parseXmlDoi(xmlDoc)
{
var $xml = $(xmlDoc);
// ...now, use $xml.find...//
}
通过告诉jQuery将响应视为XML,您将获得一个已解析的XML文档传递到您的成功函数中。然后我们使用$()
将该XML文档包装在jQuery实例中,以便在其上使用find
。

好的,我得到了答案:
我设法从Ajax url
中的POST
获取了确切的xml,因此除了header
信息之外,响应变为相同。
并编辑了我对此的Ajax调用:
$.ajax({
url:"<?php echo site_url('con/met/') ?>",
type:"POST",
data:{doi : $('input:text[name=ident]').val()},
dataType: "html", //this should be html because the php page uses echo to give data back
success: function(data)
{
var xml;
if (jQuery.browser.msie) { //for IE
xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.loadXML(data);
} else { //for non IE
xml = data;
}
parseXmlDoi(xml);
}
});
