Question

我如何将参数传递给filterText（）方法，因为我将在多个地方调用相同的方法，id是＆＃39; filterText＆＃39;和班级名称是＆＃39;内容＆＃39; ，这两个值我想作为参数传递。

＆＃13;

function filterText() {
  var rex = new RegExp($('#filterText').val());
  if (rex == "/all/") {
    clearFilter()
  } else {
    $('.content').hide();
    $('.content').filter(function() {
      return rex.test($(this).text());
    }).show();
  }
}


function clearFilter() {
  $('.filterText').val('');
  $('.content').show();
}

在上面的html中，我想参数化id（＆＃39; filterText＆＃39;）＆amp; javascript函数的类名（＆＃39;内容＆＃39;）。

Answer 1

也许你可以这样试试：

function filterText(id, class)
     {  
         var rex = new RegExp(id);
         if(rex =="/all/"){clearFilter()}else{
             $('.'.class).hide();
             $('.'.class).filter(function() {
             return rex.test($(this).text());
             }).show();
     }
     }

Answer 2

将参数传递给JS函数很简单：

声明函数时声明如下：

function filterText(param1, param2)
     {  
         var rex = new RegExp($(param1).val());
         if(rex =="/all/"){clearFilter()}else{
             $(param2).hide();
             $(param2).filter(function() {
             return rex.test($(this).text());
             }).show();
     }
     }

调用此函数时，请调用它：

filterText('#filterText','.content');

您可以将任何类型的选择器作为参数传递，它不会限制您仅传递id或仅传递类作为参数。

好吧，如果你有一个选择

$(function(){
   // For your one select
   $('#select').change(function(){
    var ref = $(this);
    filterText(ref.val())
   });
});

如果你想要任何带有filterText类的元素可以工作：

<input type="text" class="filterText" value=""/>

function filterText(value) {
  var rex = new RegExp(value || '');
  if (rex == "/all/") {
    clearFilter()
  } else {
    $('.content').hide();
    $('.content').filter(function() {
      return rex.test($(this).text());
    }).show();
  }
}

$(function(){
    // For any filter
   $('.filtertext').change(function(){
    var ref = $(this);
    filterText(ref.val());
   });
});

内联

onchange="filterText($(this).val())"

同时编辑filterText函数以获得额外参数
