Question

请我在开始输入input时需要根据css的条件（例如text-align:right或'direction:rtl）自动将用户的语言更改为阿拉伯语而不是英语

我发现下面的脚本可以做到这一点，但是由于我是初学者，因此我无法对其进行修改以使其与下面的input text或任何其他输入一起使用。

function convert2Ar(id, lang) {
    if (lang == 'ar') {
        var convert = true;
        var selectall = false;
        var cursorindx = 0;

        $('#' + id).bind('keydown', function (e) {
            if (e.shiftKey && e.altKey) {
                convert = false;
            }
            if (e.keyCode == 65 && e.ctrlKey) {

                selectall = true;

            }
        });

        $('#' + id).bind('keypress', function (e) {
            if (selectall) {
                this.select();
                selectall = false;
            }
            else if (e.keyCode != 8 && e.which != 0 && convert) {
                console.log(e.keyCode);
                e.preventDefault();
                cursorindx = this.selectionStart;
                var txt = $(this).val();
                txt = txt.substring(0, this.selectionStart) + char2Ar(String.fromCharCode(e.which), e) + txt.substring(this.selectionEnd, txt.length);
                $(this).val(txt);

                this.selectionStart = cursorindx + 1;
                this.selectionEnd = cursorindx + 1;
            }
        })
    }
}

function char2Ar(c, e) {
    if (e.keyCode != 16 && e.keyCode != 18) {
        var letter = c;
        if (e.shiftKey) {

<input type="text" id="txt_MenuSearch" class="search-input ui-autocomplete-input" placeholder="search here.." autocomplete="off">

Answer 1

我的意思是您的代码是一个函数，需要这样调用：

convert2Ar('txt_MenuSearch', 'ar');

但是整个想法对我来说很奇怪，您想要实现什么？为什么不让用户更改其键盘布局？

Here is a fiddle

Answer 2

我认为它已经在这里回答了。

Right to left Text HTML input

就像在那儿所说的那样，您不需要javascript。您只需为此输入本身设置dir =“ rtl”

如果是rtl，请更改输入文字的语言
