验证json文件中的小胡子标记值 [英] validate mustache tag value from json file

问题描述

您好，我无法在显示标签之前找到如何验证标签的方法，例如:如果我有JSON文件，可以说以下值:

Hi I havent been able to find how to validate a tag before displaying it, for instance: if I have a JSON file lets says this values:

{ "weeks":
  [
    {
      "monday800": "no",
      "monday830": "available",
      "tuesday800": "available",
      "tuesday830": "no",
      "name": "TEST"
    }
  ]
}

我带来这样的价值:

$(function(){
    $.get("data.json",function(data){
        var template = $("#tpl").html();
        var html = Mustache.to_html(template,data);
        console.log ();
        $("#information").html(html);
    });
});

现在我要做的是: if {{monday830}} == "available" then display {{name}}

Now what I want to do is: if {{monday830}} == "available" then display {{name}}

推荐答案

在胡须中是不可能的，因为其逻辑较少.改为使用 handlebarsjs .

Its not possible in mustache as its logic less. Use handlebarsjs instead.

如果您仍然想在小胡子上做到这一点，那么:

If you still want to achieve this in mustache then:

您不能使用任何if语句，但是可以检查是否存在任何东西或它的值为true.

You can not use any if statement but you can check if anything exist or its value is true.

在这种情况下，您必须像这样更新json:

if this case you have to update json like:

{ "weeks": [    {
      "monday800": "no",
      "monday830": "available",
      "monday830_available": true, // you have to add another property here
      "tuesday800": "available",
      "tuesday830": "no",
      "name": "TEST"
     }
   ]
 }

然后您可以检查

{{#monday830_available}}
     ..............
{{/monday830_available}}
