Jquery 模板 - else if 构造

发布于 2024-10-17 04:33:02 字数 737 浏览 0 评论 0原文

我试图在 jquery 模板块中使用“else if”语句。我在其他示例中看到，我们可以不写 if else，而只写 else。但这对我不起作用，它会在模板。有人可以帮忙吗？

它的实际工作方式就像

if(Amount == "")
{
-
}
else if(balance == "")
{
*
}
else
{
Amount
}

我在下面提到的 jquery 模板语法一样，我编写它是为了实现这一点。

<script id="MyTemplate" type="text/x-jquery-tmpl">
    <tr style="background-color:#EFF3FB"><td onclick="test();">${CardNumber}</td><td>${PostDate}</td>
            <td>{{if (Amount == "")}}-
                {{else(balance == "")}}*                      
                {{else}}${Amount}
                {{/if}}
             </td>
             <td>${Description}</td></tr>
    </script>

原文

I was trying to use an "else if" statement inside the jquery template block.I have seen in other samples that instead of writing if else, we can just put else.But this is not working for me, its throwing syntax error on the template.can any one help pls?

The acutual way it should work is like

if(Amount == "")
{
-
}
else if(balance == "")
{
*
}
else
{
Amount
}

I have mentioned below the jquery template syntax which i wrote to acheive this.

<script id="MyTemplate" type="text/x-jquery-tmpl">
    <tr style="background-color:#EFF3FB"><td onclick="test();">${CardNumber}</td><td>${PostDate}</td>
            <td>{{if (Amount == "")}}-
                {{else(balance == "")}}*                      
                {{else}}${Amount}
                {{/if}}
             </td>
             <td>${Description}</td></tr>
    </script>

根据 JQuery API，语法是正确的。也许尝试删除 '(' 括号？

{{if Amount == ""}}
   -
{{else balance == ""}}
   *                      
{{else}}
   ${Amount}
{{/if}}

The syntax is correct as per JQuery API. Maybe try removing the '(' parentheses?

{{if Amount == ""}}
   -
{{else balance == ""}}
   *                      
{{else}}
   ${Amount}
{{/if}}

在循环内执行 if 语句、对循环的某个项目执行 if 语句时，我遇到了类似的问题。

假设您出于同样的原因遇到问题（我发现您的问题包括一些 td 和 tr，因此您可能会迭代项目并在那么这是我的答案：

<script type="text/x-jquery-tmpl" id="jqTemplate">
 <ul>
      {{each data.messagetext}}
         <li>
             Message # ${$index+1}: "${$value}" |
             Test result: {{if $value}}exists{{else}}does not exist{{/if}}
         </li> 
      {{/each}}
    </ul>
</script>

注意 {{if $value}} 中的美元符号，这是常规 {{if value}} 的技巧，

如果你想要检查您正在迭代的项目的字段，可以执行 {{if $value.fieldname}}exists{{else}}does not exit{{/if}}

I had a similar issue when performing an if statement inside a loop, when doing the if statement on an item of the loop.

Assuming you are having an issue for the same reason (I see that your question includes some td and tr so you're probably iterating through items and displaying the their content in a table. Then here is my answer:

<script type="text/x-jquery-tmpl" id="jqTemplate">
 <ul>
      {{each data.messagetext}}
         <li>
             Message # ${$index+1}: "${$value}" |
             Test result: {{if $value}}exists{{else}}does not exist{{/if}}
         </li> 
      {{/each}}
    </ul>
</script>

notice the dollar sign in {{if $value}}, this is the trick on the regular {{if value}}

if you want to check the field of an item you are iterating on you can do {{if $value.fieldname}}exists{{else}}does not exist{{/if}}
