问题描述

只是一个小问题,我现在不能让我的头脑:



我有一个表中列出的对象。其中一个对象值是一个分数。我可以使用Django模板标签将其显示为数字,但是我想使用我的jQuery插件来显示星号。不知道如何迭代这个。我正在尝试:

  {%for mylist%} 

< td> {{result.type}}< / td>
< td> {{result.description}}< / td>
< td> {{result.rating.votes}}< / td>

< td>< div class =ratydata-number ={{result.rating.score}}>< / div>< / td>

{%endfor%}

进一步下来我得到这个: / p>

 < script> 
$('。raty')。raty({readOnly:true,score:$('。raty')。attr('value')});
< / script>

问题是它显示与jquery的每个对象相同的分数..



编辑:我得到了这个工作:

 < script> 
$('。raty')。each(function(){
$(this).raty({readOnly:true,score:$(this).attr('data-number')} );
});
< / script>


解决方案

A div 元素没有属性。尝试使用隐藏的输入元素。这样的一个例子:

 < table> 
{%for mylist%}
< tr>< td>< input type ='hidden'class ='hidden_​​score'value ='{{result.rating.score}}' >< / input>< div class =raty>< / div>< / td>< / tr>
{%endfor%}
< / table>

然后在您的脚本中:



<$ p $($('。hidden_​​score'),function(index,value){
var myval = $(this).val();
$(这个).parent()。find('.raty')。raty({readOnly:true,score:myval});
});

因此,对于每个具有hidden_​​score类的元素,您将获得其值为 这些元素属于每个元素的父母(所以他们是兄弟姐妹),具有正确的分数。


Just a small problem i can't get my head around right now:

I have a list of objects presented in a table. One of the objects values is a score. I can use a Django template tag to show this as a number but i want to use my jquery plug-in to show stars instead. Not sure how to iterate over this. I'm trying this:

{% for result in mylist %}

<td>{{ result.type }}</td>
<td>{{ result.description }}</td>
<td>{{ result.rating.votes }}</td>

<td><div class="raty" data-number="{{ result.rating.score }}"></div></td>

{% endfor %}

And further down i got this:

<script>
$('.raty').raty({ readOnly: true, score: $('.raty').attr('value') });
</script>

The problem is that it shows the same score for every object with the jquery..

EDIT: I got it to work with this:

<script>
$('.raty').each(function() {
  $(this).raty({ readOnly: true, score: $(this).attr('data-number') });
});
</script>

解决方案

A div element does not have a value attribute. Try using a hidden input element. Something like this:

<table>
    {% for result in mylist %}
        <tr><td><input type='hidden' class='hidden_score' value='{{ result.rating.score }}'></input><div class="raty"></div></td></tr>
     {% endfor %}
</table>

And then in your script:

$.each($('.hidden_score'), function( index, value ) {
    var myval = $(this).val();
    $(this).parent().find( '.raty').raty({ readOnly:true, score:myval});
});

So, for each of elements having a class of hidden_score, you will get their value make a "raty" with the elemens belonging to the parent of each element (so they are siblings) with the correct score.
