Uncaught TypeError: Cannot call method 'replace' of null
提问by sparkle
If I type "_.template($('#pranks-list').html())" on Chrome JS console it's works as well
如果我在 Chrome JS 控制台上输入“_.template($('#pranks-list').html())”，它也能正常工作
>> _.template($('#pranks-list').html())
function (a){return e.call(this,a,b)}
app.js // Views
app.js // 视图
window.PranksListView = Backbone.View.extend({
template: _.template($('#pranks-list').html())
});
Index.html
索引.html
<script type="text/html" id="pranks-list">
<li><a href='#pranks/<%= id %>'><%= name %></a></li>
</script>
</body>
Why I get this error on this line??
为什么我在这条线上收到这个错误？
template: _.template($('#pranks-list').html())

It's hard to tell without seeing the whole code, but you are probably trying to run _.template($('#pranks-list').html())before the dom is created and the node is there.
Usually its a good practice to render the template on render time when you have the template variables ready:
如果没有看到完整的代码，很难判断，但是您可能正在尝试_.template($('#pranks-list').html())在创建 dom 并且节点在那里之前运行。通常，当您准备好模板变量时，在渲染时渲染模板是一个好习惯：
_.template($('#pranks-list').html(), {id: 'foo', name: 'bar'});
