如何使用此代码进行ajax实时搜索,选择选项?
<script type="text/javascript">
$j(document).ready(function() {
$j('#keyword').on('input', function() {
var searchKeyword = $(this).val();
if (searchKeyword.length >= 0) {
$.post('search.php', { keywords: searchKeyword }, function(data) {
$j('ul#content').empty()
$.each(data, function() {
$j('ul#content').append('*<a href="reserve.php' + this.id + '">' + this.title + '</a>');
});
}, "json");
}
});
});
</script>
此代码适用于输入类型[&#39; text&#39;],如:
<input type="text" class="form-control" id="keyword" />
但我希望它适用于:
<select name="field" id="keyword">
<option value="1">sometext</option>
<option value="2">sometext</option>
<option value="3">sometext</option>
<option value="4">sometext</option>
</select>
如何使用上面的代码获取所选选项的值?
已解决:
<script type="text/javascript">
$j(document).ready(function() {
$j('#keyword').on('change', function() {
var searchKeyword = $("#keyword option:selected").val();;
if (searchKeyword.length >= 0) {
$.post('search.php', { keywords: searchKeyword }, function(data) {
$j('ul#content').empty()
$.each(data, function() {
$j('ul#content').append('*<a href="reserve.php' + this.id + '">' + this.title + '</a>');
});
}, "json");
}
});
});
</script>
