你應該綁定到適當的事件。我認爲你應該綁定到close event。然後檢查value of input包含元素in array。否則,您應該使用val再次輸入空。我自己在本地測試它,它確實有效。
$("#tags").autocomplete({
source: availableTags,
close: function(event, ui) {
var inputValue = $("#tags").val();
var idx = jQuery.inArray(inputValue, availableTags);
if (idx == -1) {
$("#tags").val("");
}
}
});
P.S:我做了一些更多的測試,我認爲你應該把它綁定到另一個事件來代替。因爲當你選擇導航欄時它不起作用。我想你應該綁定到blur事件。
的改進的代碼=>
$("#tags").autocomplete({
source: availableTags
});
$("#tags").blur(function() {
var inputValue = $("#tags").val();
var idx = jQuery.inArray(inputValue, availableTags);
if (idx == -1) {
$("#tags").val("");
}
});
JSON來陣列=>
json.txt:
[{"id":1,"value":"ActionScript"},{"id":2,"value":"AppleScript"},{"id":3,"value":"Asp"},{"id":4,"value":"BASIC"},{"id":5,"value":"C"},{"id":6,"value":"C++"},{"id":7,"value":"Clojure"},{"id":8,"value":"COBOL"},{"id":9,"value":"ColdFusion"},{"id":10,"value":"Erlang"},{"id":11,"value":"Fortran"},{"id":12,"value":"Groovy"},{"id":13,"value":"Haskell"},{"id":14,"value":"Java"},{"id":15,"value":"JavaScript"},{"id":16,"value":"Lisp"},{"id":17,"value":"Perl"},{"id":18,"value":"PHP"},{"id":19,"value":"Python"},{"id":20,"value":"Ruby"},{"id":21,"value":"Scala"},{"id":21,"value":"Scheme"}]
$(function() {
var LIMIT = 10;
$.getJSON("json.json", function(data) {
var autocomplete = $("#tags").autocomplete({
source: function(request, response) {
var i=0;
var result = [];
$.each(data, function(index, value) {
// value.value.search(/request.term/i);
var idx = value.value.toLowerCase().indexOf(request.term.toLowerCase());
if (idx >= 0) {
result.push(value.value);
i++;
}
if (i === LIMIT) {
return false;
}
});
response(result);
}
});
$("#tags").blur(function() {
var inputValue = $("#tags").val();
var clear = true;
$.each(data, function(index, value) {
if (value.value == inputValue) {
clear = false;
return false;
}
});
if (clear) {
$("#tags").val("");
}
});
});
});
如果源是一個返回json的url,該怎麼辦? – oshirowanen 2011-01-28 11:04:19
