更改语言后更改文本对齐 [英] Change Text Align After Change Language

问题描述

我在HTML中有这样的文本区域:

I have a text area in HTML like this:

<textarea name="tx1" style="direction:ltr;"></textarea>

现在，当用户将语言更改为阿拉伯语时，我想更改输入文本的方向或对齐它们. Whithout我想知道的任何问题，任何按钮或任何提交我都想知道他在输入时所用的语言.如果用户是阿拉伯语，则将textarea对齐设置为right.如果英语将其设置为左.

Now, I want to change the direction of input text or align of them when the user changes the language to arabic. Whithout Any Question or Any Button Or Any Submit I Want to know The user language when he is typing. if the user is arabic, set the textarea align to right. if english set it to left.

推荐答案

我能想到的唯一方法是检查文本区域的值

the only way i can think is checking the value of text area

var arabicPattern = /[\u0600-\u06FF]/;

$('#text').bind('input propertychange', function(ev) {

    var text = ev.target.value;

    if (arabicPattern.test(text)) {
        // arabic;
        $('#text').css('direction', 'rtl')

    }


});

但是仅检查阿拉伯语是不够的.您必须检查每个rtl脚本

But for checking only for arabic is not enought. You must check for every rtl scripts
