無法調用未定義的 handlebars.js 的方法“匹配”

Question

我正在嘗試在 PHP 中使用handlebars.js 。 我正在獲取通過$_GET傳遞的變量構建一個數組，然后將其附加到http://my.service.example.com/search.json?. http_build_query($myarray, '', "&"); http://my.service.example.com/search.json?. http_build_query($myarray, '', "&"); 構建我的 URL，然后使用file_get_contents獲取 JSON。 我正在嘗試使用handlebars.js來顯示結果。 我在 Google chrome 控制台中收到以下錯誤

“未捕獲的類型錯誤：無法調用未定義 cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:431 的方法‘匹配’”

在控制台中查看錯誤的詳細信息時，我看到了這個

lexer.next
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:431
lex
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:468
lex
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:238
parse
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:251
Handlebars.parse
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:595
compile
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:1842
(anonymous function)
cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.rc.1.js:1851
(anonymous function) profile.php:39

這是我正在使用的模板

<script id="ul" type="text/x-handlebars-template">
  <ul>
   {{#jsonResult}}
     <li>{{name}}</li>
   {{/jsonResult}}
  </ul>
</script>

這是我試圖使用模板的腳本

var source = $("ul").html();
var template = Handlebars.compile(source);
var json = $pJSON;
var data1 = JSON.stringify(json);
var data = JSON.parse(data1);
$("body").html(template(data));

這是$("body").html(template(data));上方控制台錯誤中引用的第 39 行

最后這是我得到的 JSON（以及一個示例）

Answer 1

{{#jsonResult}}
  <li>{{name}}</li>
{{/jsonResult}}

#jsonResult不會像您希望的那樣遍歷列表。 你需要使用：

{{#each jsonResult}}
  <li>{{name}}</li>
{{/each}}

請參閱http://handlebarsjs.com#iteration 。

您還需要更改var source = $("ul").html(); 到var source = $("#ul").html();
