j Query模板中的条件操作者
原标题:Conditional operator in jQuery template

新的“金色”模版支持有条件(永久)经营者吗? 印刷一种简单价值,视具体情况而定,为{>{>>>>>。 唯一的选择?

我有兴趣了解与<代码>和”相类似的一些东西? ham :spiam ?>

最佳回答

是的,你可在>${ 模板标记:

Evaluates the specified field (property) on the current data item, or the specified JavaScript function or expression.

${reviewed ?  ham  :  spam }

因此,你可以撰写这样一个模板:

<script id="movieTemplate" type="text/x-jquery-tmpl">
    <!-- Ternary operator to assign a class -->
    <li class="${Year >= 1990 ?  orange  :  yellow }">
        Title: ${Name}.
        {{each Languages}}
            ${$index + 1}: <em>${$value}. </em>
        {{/each}}
    </li>
</script>

鉴于 Java本和JSON等数据:

var movies = [
{
    Name: "Meet Joe Black",
    Languages: ["French"],
    Year: 1990
}, 
{
    Name: "The Mighty",
    Languages: [],
    Year: 1985
}, 
{
    Name: "City Hunter",
    Languages: ["Mandarin", "Cantonese"],
    Year: 1994
}];

$("#movieTemplate").tmpl(movies).appendTo("#movieList");

这适用于超过1990年或等于1990年的电影,以及比1990年少的电影的黄色。
