如何禁用 javascript 对分隔输入字段的影响？

Question

这是在每个输入和文本区域字段中打开格鲁吉亚键盘的 Javascript

但是我有一个ID为user_login的输入字段，类型是文本，当然，这个javascript也对这个字段生效我只是想仅针对 ID 为 user_login

的字段禁用此 javascript 的效果

请帮帮我提前谢谢你

如果您在 form 元素而不是复选框上调用您的插件，然后在文档中搜索所有需要的元素类型，但带有 id 或 user_login 的元素类型除外，您的 inputs JQuery 包装器将只包含您想要的元素。

(function($, undefined) {

$.fn.geokbd = function(options) {
    var 
    isOn, 
    inputs = $([]),
    switchers = $([]),
    defaults = {
        on: true,
        hotkey: '`'
    },
    settings = (typeof options === 'object' ? $.extend({}, defaults, options) : defaults);

    // first come up with affected set of input elements
    // Using the standard DOM API, search the document for all `input` and 
    // 'textarea' elements, except for the one with an id of: "user_login"
    document.querySelectorAll("input:not(#user_login), textarea").forEach(function(item) {
        var $this = $(item);
        // You had the selector for an input incorrect
        if ($this.is('input[type="text"], textarea')) {
            inputs = inputs.add($this);
        } else if ($this.is('form')) {
            inputs = inputs.add($this.find('input[type="text"], textarea'));
        } else if ($this.is(':checkbox')) {
            if (!inputs.length) {
                inputs = $('input[type="text"], textarea');
            }
            switchers = switchers.add($this); // store the checkboxes for further manipulation
        }

        if (typeof settings.exclude === 'string') {
            inputs = inputs.not(settings.exclude);
        }
    });

    // mutate switchers
    switchers
        .click(function() { toggleLang() })
        .wrap('<div class="gk-switcher"></div>')
        .parent()
