我有一个配方API,它有不同类型的配方:Starter,Main,Dessert等。
我想做的是在一次调用中从API中获取所有数据,并让把手根据“类别”字段填充特定模板(这些模板相同但添加到不同的占位符)。但是,从下面的代码中,我将HTML注入到我的占位符div中但没有数据。奇怪的是,我也得到了4个模板数据实例。
这是我的代码:
对API的jQuery AJAX调用:
$( document ).ready(function() {
$.ajax({
type: "GET",
url: "http://example.org/api/recipes",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
var source;
var template;
$.each(msg, function (i, o) {
if (o['Category'] === "Starter") {
source = $("#startertemplate").html();
template = Handlebars.compile(source);
$("#starters").html(template(o));
} else if (o['Category'] === "Main") {
source = $("#maintemplate").html();
template = Handlebars.compile(source);
$("#main").html(template(o));
}
});
}
});
});
把手模板:
<script id="startertemplate" type="text/x-handlebars-template">
{{#each this}}
<div class="col-sm-6">
<h3>{{Title}}</h3>
<img src="{{ImagePath}}" alt="{{Title}}" height="200" width="300" /><br />
<a href="recipe.html?id={{ID}}">See more</a>
</div>
{{/each}}
</script>
<script id="maintemplate" type="text/x-handlebars-template">
{{#each this}}
<div class="col-sm-6">
<h3>{{Title}}</h3>
<img src="{{ImagePath}}" alt="{{Title}}" height="200" width="300" /><br />
<a href="recipe.html?id={{ID}}">See more</a>
</div>
{{/each}}
</script>
示例JSON:
[
{"ID":1,"Title":"Aioli","Category":"Starter","ImagePath":"/assets/recipes/Aioli.jpg"},
{"ID":3,"Title":"Asparagus and Parmesan Tartlets","Category":"Starter","ImagePath":"/assets/recipes/Asparagus_and_Parmesan_Tartlets.jpg"},
{"ID":4,"Title":"Broad Bean Pate with Melba Toasts","Category":"Main","ImagePath":"/assets/recipes/Broad_bean-pate.jpg"}
]
我出错的任何想法?
答案 0 :(得分:2)
首先,您需要将食谱分成不同的列表。
var starterList = [],
mainList = [];
$.each(msg, function (i, o) {
if (o['Category'] === "Starter") {
starterList.push(o);
} if (o['Category'] === "Main") {
mainList.push(o);
}
});
然后立即将模板提供给模板。
$("#starters").html(templateStarter(starterList));
$("#main").html(templateMain(mainList));
这是一个有效的jsfiddle。
