如何使用另一种方法：创建输入时初始化自动完成功能：
$(function() { // settings for each autocomplete var autocompleteOptions = { minLength: 3, source: function(request, response) { $.ajax({ type: "GET", url: "getNames.html", data: { name: request.term }, success: function(data) { response(data); } }); } }; // dynamically create an input and initialize autocomplete on it function addInput() { var $input = $("<input>", { name: "search", "class": "searchInput", maxlength: "20" }); $input .appendTo("form#myForm") .focus() .autocomplete(autocompleteOptions); }; // initialize autocomplete on first input $("input.searchInput").autocomplete(autocompleteOptions); $("input#addButton").click(addInput);});<form id="myForm" name="myForm" method="post"> <input id="addButton" type="button" value="Add an input" /> <input name="search" maxlength="20" /></form>jsFiddle与AJAX
