查询方法的问题，从html data- *属性翻译一次

Question

所以我正在尝试实现一种方法来翻译我的页面中的内容而不使用多余的html5 data- *属性来刷新它，在这种情况下，data-en用于存储英语翻译文本。我正在从西班牙语翻译成英语。

我的代码做了什么，或者应该做什么，因为它不起作用：

- 使用数据属性“data-en”存储所有p元素。 - 通过p元素与for。 - 将“data-en”的值存储到变量“trans”中。 - 用“trans”变量替换p元素的文本。

以下是代码：

$(document).ready(function(){
var i = 0;
var trans;
$('.settingswheel').click(function(){
atraducir = $('p[data-en]');
for (i = 0; i < atraducir.length; i++) {
  trans = atraducir[i].text(atraducir[i].data('en'));
  atraducir[i].text(trans);      
}
});
});

Answer 1

您可以使用.text(fn)

$('.settingswheel').click(function () {
    $('p[data-en]').text(function () {
        return $(this).data('en');
    });
});

在代码段中，我使用了<BUTTON>来附加click事件处理程序。

＆＃13;

＆＃13;

$(document).ready(function() {
  $('.settingswheel').click(function() {
    $('p[data-en]').text(function() {
      return $(this).data('en');
    });
  });
});

＆＃13;

＆＃13;

使用.eq(index)访问索引处的元素，然后.data()可以使用.text()。

$('.settingswheel').click(function () {
    atraducir = $('p[data-en]');
    for (i = 0; i < atraducir.length; i++) {
        var elem = atraducir.eq(i); //Get element at index
        trans = elem.data('en'); //Get Data
        elem.text(trans); //Set text
    }
});

＆＃13;

＆＃13;

$(document).ready(function() {
  var i = 0;
  var trans;
  $('.settingswheel').click(function() {
    atraducir = $('p[data-en]');
    for (i = 0; i < atraducir.length; i++) {
    var elem = atraducir.eq(i);
      trans = elem.data('en');
      elem.text(trans);
    }
  });
});

Answer 2

试试这个

$(document).ready(function(){
    $('.settingswheel').click(function(){
        atraducir = $('p[data-en]');

        for (i = 0; i < atraducir.length; i++) {
            atraducir[i].innerText = atraducir[i].dataset.en
        }
    });
});
