Underscore js - Uncaught SyntaxError: Unexpected token if
Underscore js - Uncaught SyntaxError: Unexpected token if
我用的是小胡子插值:
_.templateSettings = {
interpolate: /\{\{(.+?)\}\}/g
};
对于这段代码,我收到错误:Uncaught SyntaxError: Unexpected token if
<div class="d-none flex-container tip-container bg-white mt-5" data-ajax-template-empty-tip>
<div class="tip-header border border-bottom-0 d-flex flex-row p-2">
<div class="align-self-center mr-2">
<a href="./{{countryName}}" target="_blank">
<img class="d-block" alt="" src="/images/flags/{{countryId}}.png">
</a>
</div>
{{if (typeof(cityName) !== "undefined") { }}
<i class="fas fa-arrow-left align-self-center mr-2"></i>
<div class="align-self-center mr-2">
<a class="badge badge-primary" role="button" href="/city/{{cityName}}" target="_blank">
<span>{{cityName}}</span>
</a>
</div>
{{}}}
</div>
</div>
没有 if 语句它工作得很好,但是有它就不行了,知道哪里出了问题吗?我在网上看了每一个问题都想不通,我什至删除了插值并使用默认的 <% 但它不会。
在 if 之前尝试一个 space,像这样:
{{ if (typeof(cityName) !== "undefined") { }}
我必须添加此设置才能使其正常工作:
_.templateSettings = {
evaluate: /\{\{(.+?)\}\}/g,
interpolate: /\{\{=(.+?)\}\}/g,
escape: /\{\{-(.+?)\}\}/g
};
