led*_*per 2 html javascript mustache handlebars.js
这个问题有点像我的JS技能,所以我可能会像白痴一样解释它.
这是我从服务器获取json的JavaScript,并尝试将其推送到模板中:
//Server Interface Start
//Access the web api for The User:
var lucidServer = (function () {
//global error handler
$(document).ajaxError(function (event, xhr) {
alert(xhr.status + " : " + xhr.statusText);
});
//client Calls
var getClients = function (id) {
return $.ajax(clientUrl + "/list/" + id)
};
var getClient = function (id) {
return $.ajax(clientUrl + "/details/" + id)
};
//push them out to the world!
return {
getClients: getClients,
getClient: getClient,
};
}());
//Server Interface End
(function () {
//list of clients
var refreshClients = function () {
lucidServer.getClients(1).done(showAllClients);
};
var showAllClients = function (templateInput) {
var source;
var template;
var path = '../Templates/indexTemplates.html'
$.ajax({
url: path,
cache: true,
success: function (data) {
source = data;
template = Handlebars.compile(source);
$('#clientListOutput').html(template(templateInput));
}
});
};
$(function () {
refreshClients();
});
}());
GetClients工作正常,并返回我期待的Json数据.当我检查templateInput时,它显示了我的期望.
这是外部模板:
<script id="clientList" type="text/html">
<div id="clients">
{{#each client}}
<span data-id="{{this.iD}}" />
<div>
<p>{{this.iD}}</p>
<p>{{this.name}}</p>
</div>
{{/each}}
</div>
</script>
我最终的目标是将所有模板保存在一个html文件中,我可以通过脚本id调用,或者让每个模板都是我自己可以调用的文件.当我运行此页面时,没有任何显示,没有任何错误或任何错误.这是整个索引页面:

我改变了模板看起来的方式.通过调试Chrome工具中的js,它告诉我在showallclients中的ajax成功行中未定义"数据".
您需要使用getClient返回的数据调用模板.在您的示例中,showAllClients的参数被成功回调中的参数遮蔽,因为您使用相同的名称(数据).将showAllClients中的参数名称更改为其他名称,并将其传递给模板函数.
(function () {
//list of clients
var refreshClients = function () {
$.when(lucidServer.getClients(1)).done(showAllClients);
};
var showAllClients = function (templateInput) {
var source;
var template;
var path = 'Templates/indexTemplates.html'
$.ajax({
url: path,
cache: true,
success: function (data) {
source = data;
template = Handlebars.compile(source);
$('#clientListOutput').html(template(templateInput));
}
});
};
$(function () {
refreshClients();
});
}());
编辑:
在模板中,您需要this在每个块内引用:
<div id="clients">
{{#each client}}
<span data-id="{{this.id}}">
<div>
<p>{{this.iD}}</p>
<p>{{this.name}}</p>
...
</div>
{{/each}}
</div>
在您的示例中,您使用嵌套迭代器,我不确定是否支持它.请阅读如何使用Mustache.js或Handlebars.js嵌套迭代器？或Ember.js/Handlebars嵌套每个迭代以获得不同的方法.
