我有一个输入文本框,每次用户输入数据并填充输入文本时都会触发。我正在使用bootstrap typehead
. 问题是当我输入一个字母a
时,它会触发 ajax jquery 调用并获取数据,但没有填充输入文本框。现在,当aw
输入另一个字母时,针对字母 a 提取的数据会填充到文本区域中。
我在这里托管了代码http://hakunalabs.appspot.com/chartPage
好的,这是我的 html 代码的一部分
<script type="text/javascript">
$(document).ready(function () {
$('#txt').keyup(function () {
delay(function () {
CallData();
}, 1000);
});
});
var delay = (function () {
var timer = 0;
return function (callback, ms) {
clearTimeout(timer);
timer = setTimeout(callback, ms);
};
})();
</script>
<input type="text" id="txt" runat="server" class="span4 typeahead local remote" placeholder="Search..." />
这是我的javascript代码
var DataProvider;
function CallData() {
DataProvider = [];
var vdata = $('#txt').val();
if (vdata != "") {
var urlt = "http://examples/search?keyword=" + vdata + "&callback=my_callback";
$.ajax({
type: "GET",
url: urlt,
jsonpCallback: "my_callback",
dataType: "jsonp",
async: false,
error: function (xhr, errorType, exception) {
var errorMessage = exception || xhr.statusText;
alert("Excep:: " + exception + "Status:: " + xhr.statusText);
}
});
}
}
function my_callback(data) {
var NameArray = new Array();
var descArray = new Array();
for (var i = 0; i < data.count; i++) {
NameArray.push(data.response[i].days_till_close + " Days Left | " + data.response[i].name + " | " + data.response[i].description);
}
for (var i = 0; i < data.count; i++) {
descArray.push(data.response[i].description);
}
DataProvider = [];
for (var i = 0; i < data.count; i++) {
var dataObject = { id: i + 1, name: NameArray[i], description: descArray[i] };
DataProvider.push(dataObject);
}
var vdata = $('#txt').val();
var urlp = "http://example.com/v1/members/search?keyword=" + vdata + "&my_callbackMember";
$.ajax({
type: "GET",
url: urlp,
jsonpCallback: "my_callbackMember",
dataType: "jsonp",
error: function (xhr, errorType, exception) {
var errorMessage = exception || xhr.statusText;
alert("Excep:: " + exception + "Status:: " + xhr.statusText);
}
});
}
function my_callbackMember(data) {
var memberArray = new Array();
for (var i = 0; i < data.count; i++) {
memberArray.push(data.response[i].name);
}
for (var i = 0; i < data.count; i++) {
var dataObject = { id: i + 1, name: memberArray[i] };
DataProvider.push(dataObject);
}
localStorage.setItem("name", JSON.stringify(DataProvider));
var sources = [
{ name: "local", type: "localStorage", key: "name", display: "country" }
];
$('input.typeahead.local.remote').typeahead({
sources: [{ name: "", type: "localStorage", key: "name", display: "name"}],
itemSelected: function (obj) { alert(obj); }
});
