我正在使用 jquery 自动完成文本区域。我希望每当我按“空格键”时就调用自动完成功能。只有第一次才可以正常工作。有人可以帮我解决这个问题吗？**
我使用了以下代码：
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"> </script>
<script src="http://code.jquery.com/ui/1.8.18/jquery-ui.min.js" type="text/javascript"></script>
<script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.2.js" type="text/javascript"></script>
<script src="http://jquery-ui.googlecode.com/svn/tags/latest/ui/minified/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script>
<script>
function auto_comp(flag1)
{
$(function() {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme",
"{ }"
];
if(flag1 == 1)
{
$( "#tags" ).autocomplete({
source: availableTags
});
}
});
}
</script>
<div class="demo">
<div class="ui-widget">
<textarea id="tags" name="get" rows="5" cols="31"></textarea>
<script>
var charfield=document.getElementById("tags");
var flag=0;
charfield.onkeypress=function(e){
var e=window.event || e;
var keyunicode=e.charCode || e.keyCode;
if(keyunicode == '97'|| keyunicode == '65')
{
flag=1;
auto_comp(flag);
}
document.getElementById("unicode").value=keyunicode;
}
</script>
</body></html>
