我试图根据用户标准创建一个搜索用户的页面。然后它通过AJAX响应将结果加载到不同的DIV中:
function search_friends() {
$("#search-results").show();
$("#loading1").show();
var q = $("#id_q").val();
var type = $("#id_search_type").val();
$("#loading1").hide();
$("#results").load("/search/friends/?ajax&q="+encodeURIComponent(q)+"&search_type="+encodeURIComponent(type));
return false;
}
在这个新结果DIV中,我为每个用户提供了链接,以便能够将它们添加为朋友。此结果中的每个链接DIV都具有每个用户userID的ID和一个user_link类。当登录用户点击链接时,我希望它弹出一个确认框,然后通过AJAX发送请求。但是,我无法像我想的那样通过AJAX获取链接。我的代码如下:
{% for u in users %}
<div id="results">
<img src="{{ u.profile_pic }}" class="xsmall-pic" /> <a href="/{{ u.username }}/">{{ u.username }}</a><br />
<span class="small-date">{{ u.get_full_name }}</span>
<span class="floatR" id="user_{{ u.id }}_link"><a href="#" id="{{ u.id }}" class="user_link">Add as friend</a></span>
</div>{% endfor %}
<script type="text/javascript" language="javscript">
$(document).ready(function() {
var csrf_token = "{{ csrf_token }}";
$(".user_link").bind('click',function() {
request_friend($(this).id,csrf_token)
});
$("#search-friends-form").submit(search_friends);
});
</script>
在外部JavaScript文件中,我有以下内容:
function confirm_request()
return confirm("Are you sure you want to request this user as a friend?");
}
function request_friend(id,token)
if (confirm_request())
{
var data1 = {to_friend: id,csrfmiddlewaretoken: token};
$.post('/users/requests/friends/'+id+'/?ajax',
data1, function(json) {
$("#user_"+id+"_link").html(json.status);
}, "json");
return false;
}
else
{
return;
}
}
感谢您提供任何帮助,因为我对Javascript并不是那么棒。

如果您想避免在AJAX响应中使用JavaScript,则可以让.load()
的完成事件负责设置点击事件:
var url = "/search/friends/?ajax&q="+encodeURIComponent(q)+"&search_type="+encodeURIComponent(type);
$("#results").load(url, function() {
var csrf_token = "{{ csrf_token }}";
$(".user_link").bind('click',function() {
request_friend($(this).id,csrf_token)
});
});

如果我理解你的问题,你想确保点击处理程序适用于通过以后的AJAX调用加载的链接吗?
在jQuery中,使用$('.user_link').live('click', function() {})
处理程序一次将click事件处理程序分配给所有当前和未来的链接。

除非您明确告诉jQuery对其进行评估,否则不会评估从您的AJAX调用返回的Javascript。这是通过在AJAX调用上指定dataType
来完成的,.load()
doesn't support。
如this answer所示,您应该使用jQuery.get()
或$.ajax
并指定您的数据类型:
$.ajax({
type: "GET",
url: "yourPage.htm",
dataType: "html"
});
