jQuery Template - Executing JS code inside the template
I am trying to learn mo开发者_如何学运维re about jQuery templates but cant seem to execute any JS calls inside the template.
<script id="log-item" type="text/x-jquery-tmpl">
{{if title.length }}
<h3 style="padding-bottom:5px;">${ title }</h3>
{{/if}}
objectToString(${ detail });
</script>
Note that my objectToString() function is never called, just rendered out as a string. I tried wrapping it in {{ }} on a whim but no luck. Anyone out there who can help?
Anthony, you can. The method your calling needs to be inside a template tag like so:
<script id="log-item" type="text/x-jquery-tmpl">
{{if title.length }}
<h3 style="padding-bottom:5px;">${ title }</h3>
{{/if}}
<p>
Detail: ${ objectToString( detail ) }
</p>
</script>
I am not sure where you have your objectToString is located, but if you see the reference here, you see them adding the necessary helper function into the .tmpl( method).
Here is an example... I tried to make it similar to what you have in the question...
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Test jquery Templates</title>
<script type='text/javascript' src='http://code.jquery.com/jquery-1.4.4.min.js'></script>
<script type='text/javascript' src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script>
</head>
<body>
<script id="testTemplate" type="text/x-jquery-tmpl">
{{if title.length}}
<h3>${title}</h3>
<p>Detail: ${$item.objectToString("detail")}</p>
{{/if}}
</script>
<div id="bookList"></div>
<script type='text/javascript'>
$(function(){
var book = [
{ title: "Goodnight, World!",
detail: { author: "Jojo Mojo", synopsis : "What the ..." }},
{ title: "Rainbow",
detail: { author: "Cookie", synopsis : "Huh?" }}
];
$("#testTemplate").tmpl(book, {
objectToString : function(key) {
var detail = this.data[key];
return detail.author + " " + detail.synopsis;
}
}).appendTo("#bookList");
});
</script>
</body>
</html>
You can see it here.
