本文翻译自：How do I call an Angular.js filter with multiple arguments?

As from the documentation , we can call a filter such as date like this: 从文档中我们可以调用像这样的日期过滤器：

{{ myDateInScope | date: 'yyyy-MM-dd' }}

Here date is a filter that takes one argument. 这里date是一个带有一个参数的过滤器。

What is the syntax to call filters with more parameters both from templates and from JavaScript code? 从模板和JavaScript代码调用带有更多参数的过滤器的语法是什么？

In templates, you can separate filter arguments by colons . 在模板中，您可以使用冒号分隔过滤器参数。

{{ yourExpression | yourFilter: arg1:arg2:... }}

From Javascript, you call it as 从Javascript，你称之为

$filter('yourFilter')(yourExpression, arg1, arg2, ...)

There is actually an example hidden in the orderBy filter docs. 实际上， orderBy过滤器文档中隐藏了一个示例。

Example: 例：

Let's say you make a filter that can replace things with regular expressions: 假设您创建了一个可以用正则表达式替换事物的过滤器：

myApp.filter("regexReplace", function() { // register new filterreturn function(input, searchRegex, replaceRegex) { // filter argumentsreturn input.replace(RegExp(searchRegex), replaceRegex); // implementation};
});

Invocation in a template to censor out all digits: 在模板中调用以检查所有数字：

<p>{{ myText | regexReplace: '[0-9]':'X' }}</p>

i mentioned in the below where i have mentioned the custom filter also , how to call these filter which is having two parameters 我在下面提到过我自己也提到了自定义过滤器，如何调用这些有两个参数的过滤器

countryApp.filter('reverse', function() {return function(input, uppercase) {var out = '';for (var i = 0; i < input.length; i++) {out = input.charAt(i) + out;}if (uppercase) {out = out.toUpperCase();}return out;}
});

and from the html using the template we can call that filter like below 从使用模板的html我们可以像下面那样调用该过滤器

<h1>{{inputString| reverse:true }}</h1>

here if you see , the first parameter is inputString and second parameter is true which is combined with "reverse' using the : symbol 在这里，如果你看到，第一个参数是inputString，第二个参数是true，它与使用：符号的“反向”组合

If you want to call your filter inside ng-options the code will be as follows: 如果要在ng-options中调用过滤器，代码如下：

ng-options="productSize as ( productSize | sizeWithPrice: product )  for productSize in productSizes track by productSize.id"

where the filter is sizeWithPriceFilter and it has two parameters product and productSize 过滤器的大小是sizeWithPriceFilter，它有两个参数product和productSize

If you need two or more dealings with the filter, is possible to chain them: 如果您需要与过滤器进行两次或更多次交易，可以将它们链接起来：

{{ value | decimalRound: 2 | currencySimbol: 'U$' }} 
// 11.1111 becomes U$ 11.11

像这样：

var items = $filter('filter')(array, {Column1:false,Column2:'Pending'});
