这是我的JSON,我想知道如何使用把手模板引擎将我的信息显示在页面中:
这是我的模板(脚本):
<script id="template-app" type="text/x-handlebars-template">
{{#each data}}
Email: {{email}} <br/>
First Name: {{first_name}} <br/>
Last Name: {{last_name}} <br/>
{{/each}}
</script>
我发送了一个ajax请求以获取以下JSON:
$(function(){
var theTemplateScript= $("#template-app").html();
var theTemplate= Handlebars.compile(theTemplateScript);
$.ajax({
url: 'http://localhost/cb/MOCK_DATA.json',
type: 'GET',
dataType: 'json',
contentType: "application/json; charset=utf-8",
success: function(data) {
var theCompiledHTML= theTemplate(data);
$(document.body).append(theCompiledHTML);
}
});
});
这是Ajax请求上面的JSON:
[{"first_name":"Betty","last_name":"Sims","email":"bsims0@studiopress.com"},
{"first_name":"Roger","last_name":"Mendoza","email":"rmendoza1@google.pl"},
{"first_name":"Albert","last_name":"West","email":"awest2@cornell.edu"},
{"first_name":"Bobby","last_name":"Lane","email":"blane3@ameblo.jp"},
{"first_name":"Julie","last_name":"Wheeler","email":"jwheeler4@google.ru"}]
它不起作用,我相信它来自我写的模板!
答案 0 :(得分:1)
这是因为你对每个data
说,循环遍历数组。但是,您将一个普通的旧数组传递给Handlebar模板。期望具有属性data
的对象和数组值。因此,您可以将Handlebars模板更改为: -
<script id="template-app" type="text/x-handlebars-template">
{{#each this}}
Email: {{email}} <br/>
First Name: {{first_name}} <br/>
Last Name: {{last_name}} <br/>
{{/each}}
</script>
-
或者,您可以调整JSON数据以使用现有的Handlebars模板,如下所示: -
var json = {
data: [{
"first_name": "Betty",
"last_name": "Sims",
"email": "bsims0@studiopress.com"
}, {
"first_name": "Roger",
"last_name": "Mendoza",
"email": "rmendoza1@google.pl"
}, {
"first_name": "Albert",
"last_name": "West",
"email": "awest2@cornell.edu"
}, {
"first_name": "Bobby",
"last_name": "Lane",
"email": "blane3@ameblo.jp"
}, {
"first_name": "Julie",
"last_name": "Wheeler",
"email": "jwheeler4@google.ru"
}]
};
对于您的JavaScript代码,您只需要进行一些更改即可获得上述JSON:
$(function(){
var theTemplateScript= $("#template-app").html();
var theTemplate= Handlebars.compile(theTemplateScript);
$.ajax({
url: 'http://localhost/cb/MOCK_DATA.json',
type: 'GET',
dataType: 'json',
contentType: "application/json; charset=utf-8",
success: function(result) {
var json_handlbars={
data:result
};
var theCompiledHTML= theTemplate(json_handlbars);
alert(theCompiledHTML);
$(document.body).append(theCompiledHTML);
}
});
});
