【问题描述】:
我有一个 Bootstrap 选择下拉菜单,我正在尝试使用 Handlebars JS 将所需的选项输出到我的选择中,但它们没有出现。我在这里阅读了一些示例,所以不确定是什么阻止了我的代码正确呈现,任何指针将不胜感激。
HTML:
<select class="custom-select" id="inputGroupSelect01" onChange="takeSelectedSourceValue(this);">
<option id="source-language" value="" selected disabled>Auto</option>
<div id="myForm"></div>
<script type="text/handlebar-template" id="selectPersonTemplate">
{{#each people}}
<option value="{{valueLang}}">{{htmlLang}}</option>
{{/each}}
</select>
</script>
<script src="https://twitter.github.io/typeahead.js/js/handlebars.js"></script>
记者:
$(function () {
// Define an array of people.
var people = [
{ valueLang: 'DE', htmlLang: 'DE' },
{ valueLang: 'FR', htmlLang: 'FR' },
{ valueLang: 'IT', htmlLang: 'IT' },
{ valueLang: 'ES', htmlLang: 'ES' },
{ valueLang: 'SV', htmlLang: 'SV' },
{ valueLang: 'DA', htmlLang: 'DA' }
];
// Get the text for the Handlebars template from the script element.
var templateText = $("#selectPersonTemplate").html();
// Compile the Handlebars template.
var selectPersonTemplate = Handlebars.compile(templateText);
// Evaluate the template with an array of people.
var html = selectPersonTemplate({ people: people });
// Take the HTML that was created with the Handlebars template and
// set the HTML in the myForm div element.
$("#myForm").html(html);
});
