我想用 ajax 在 django 中发布一些文本,并保存输入数据,在同一页面中显示数据并且不刷新,比如 twitter。
我的js:
$('#SumbitButton').click(function(){
var data_1 = $('#data_1').val()
var data_2 = $('#data_2').val()
var data_3 = $('#data_3').val()
var data_4 = $('#data_4').val()
var user = $('#AuthorName').text()
var authorprotrait = $('#UserProprait').html()
if(data_1.length>0){
$.ajax({
type: 'POST',
url: '/post/',
data:{'data_1':data_1,'data_2':data_2,'data_3':data_3,'data_4':data_4},
async: false,
error: function(msg){alert('Fail')},
success: function(msg){
$('#TopicWrap').prepend("<div class='topic-all even'><div class='topic-left'><div class='topic-author'><div class='topic-author-protrait'>"+authorprotrait+"</div><div class='topic-author-nickname'>"+authorname+"</div></div></div><div class='topic-right'><div class='topic-meta'><span class='topic-datetime'></span></div><div class='topic-content-wrap'><div class='topic-content'>"+msg+"</div></div></div><div class='clearfix'></div></div>");
$('#data_1').val('');
$('#data_2').val('');
$('#data_3').val('');
$('#data_4').val('');
}
});
} else {
alert('The data_1's length error !'+data_1.length);
}
});
和html:
<div id="TopicTextarea">
<div>
data1:<input tabindex="4" id="data_1" type="text" name="data1" value="" maxlength="6" placeholder=""/></br>
data2:<input tabindex="4" id="data_2" type="text" name="data2" value="" maxlength="8" placeholder=""/></br>
data3:<input tabindex="4" id="data_3" type="text" name="data3" value="" maxlength="10" placeholder=""/></br>
data4:<input tabindex="4" id="data_4" type="text" name="data4" value="" maxlength="10" placeholder=""/>
<div id="TopicFormControl">
<button type="button" id="SumbitButton" class="button orange">sumbit</button>
</div>
</div>
<div class="clearfix"></div>
</div>
<div id="TopicWrap">
{% include 'topics.html'%}
</div>
和意见:
@login_required
def post(request):
assert(request.method=='POST' and request.is_ajax()==True)
data_1 = smart_unicode(request.POST['data_1'])
data_2 = smart_unicode(request.POST['data_2'])
data_3 = smart_unicode(request.POST['data_3'])
data_4 = smart_unicode(request.POST['data_4'])
data_obj = DataPool(user=request.user,data_1=data_1,data_2=data_2,data_3=data_3, data_4=data_4)
data_obj.save()
content = '"+data_3+" "+data_4+" "+data_1+"("+data_2+")'
response = HttpResponse(cgi.escape(content))
return response
当我输入数据并单击 sumbit 按钮时,它可以保存数据,但不能显示数据。我的代码有什么问题?
谢谢。
