Question

Mustache是否以任何方式限制Mustache tag的特性数量?

页: 1

template = "<li>{{my_tag}}</li>"

data = {
    "my_tag" : "A very long string that needs to be abbreviated to fit into the available space."
}

Now when I render my tag I want to abbreviate the long string by showing only the first 10 chars follwed by an ellipsis. I looked into using a lambda function (as described in the Mustache docs) like so...

template = "<li>{{#limitLength}}{{my_tag}}{{/limitLength}}</li>"

data = {
    "limitLength" : function() {
        return function(text) {
          return text.substr(0,10) +  ... ;
        }
      },
    "my_tag" : "A very long string that needs to be abbreviated to fit into the available space."
}

但不幸的是,Petmy-tag 并没有扩大。《Mustache手册》指出:

The text passed is the literal block, unrendered. {{tags}} will not have been expanded - the lambda should do that on its own.

.. but I can t imagine how to do this without using the Mustache.to_html() function and when I try to use it like so...

页: 1

data = {
    "limitLength" : function() {
        return function(text) {
          return Mustache.to_html(text,data).substr(0,10) +  ... ;
        }
      },
     "my_tag" : "A very long string that needs to be abbreviated to fit into the available space."
}

......它没有保持沉默(重复使用数据标本可能会在这里被指责)

是否有任何人知道在不行使 j/Qu职能的情况下实现这一点的其他任何方式,我希望在可能时使用Mustache执行。

您的职能实际上有两种论点:未经提交的文本和<编码>render功能,可用来使案文成为原文,保持目前的情况。

data = {
    "limitLength" : function() {
        return function(text, render) {
          return render(text).substr(0,10) +  ... ;
        }
      },
     "my_tag" : "A very long string that needs to be abbreviated to fit into the available space."
}
