javascript - 对多个组合框使用相同的 ID？

Question

我需要分配一个 ID 给 jquery autocomplete Combobox 但是我有多个页面中的 jquery autocomplete Combobox 我正在使用这一行 input.attr("id", "anyThng"); 将 ID 分配给 jquery autocomplete Combobox

http://jqueryui.com/autocomplete/#combobox

引用代码:

(function($) {
    $.widget("ui.combobox", {
        _create: function() {
            var input, self = this, select = this.element.hide(), selected = select.children(":selected"), value = selected.val() ? selected.text() : "", wrapper = this.wrapper = $("<span>").addClass("ui-combobox").insertAfter(select);

            input = $("<input>")
            // .id("something")
                    .appendTo(wrapper)
                    .val(value)
                    .addClass("ui-state-default ui-combobox-input")
                    .autocomplete({
                        delay: 0,
                        minLength: 0,
                        source: function(request, response) {
                            var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
                            response(select.children("option").map(function() {
                                var text = $(this).text();
                                if (this.value && (!request.term || matcher.test(text)))
                                // alert(text);
                                    return {

ID 应该是唯一的，为什么不更改它们以共享相同的 Class 然后在您的函数中使用它。
