我已经就此问题咨询了多个主题,并尝试了许多调试方法,但尚未找到100%的解决方案。我试图在网站上实施自动填充功能。
主要问题是下拉/建议未完全显示。输入框下方显示的内容在我输入特定值时响应正确,但不完整(看起来像折叠菜单)。我错过了什么吗?
这是我的PHP:
<?php
if (!isset($web_dbi)) {
$web_dbi=new MySQLi("#", "#", "#", "#");
if ($web_dbi->connect_errno) die ("Failed to connect");
}
$sql = "query";
$result = mysqli_query($web_dbi, $sql) or die("Error " . mysqli_error($web_dbi));
$dname_list = array();
while($row = mysqli_fetch_array($result))
{
$dname_list[] = $row['first'];
}
$num_rows_result = mysqli_num_rows($result);
?>
这是我的HTML:
<!doctype html>
<html lang="en">
<head>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/smoothness/jquery-ui.css">

$(function() {
var availableTags = [ <?php echo json_encode($dname_list); ?> ];
$( "#tags" ).autocomplete({
source: availableTags
});
});
</script>
</body>
</html>
这是我的CSS:
.ui-autocomplete { position: absolute; cursor: default; }
/* workarounds */
* html .ui-autocomplete { width:1px; } /* without this, the menu expands to 100% in IE6 */
/*
* jQuery UI Menu 1.8.7

ul.ui-autocomplete.ui-menu {
z-index: 1000;
}
.ui-menu {
list-style:none;
padding: 2px;
margin: 0;
display:block;
float: left;
}
.ui-menu .ui-menu {
margin-top: -3px;

.ui-menu .ui-menu-item {
margin:0;
padding: 0;
zoom: 1;

}
.ui-menu .ui-menu-item a {

display:block;
padding:.2em .4em;

}
.ui-menu .ui-menu-item a.ui-state-hover,
.ui-menu .ui-menu-item a.ui-state-active {
font-weight: normal;
margin: -1px;
}
有没有人发现任何问题或有建议?
答案 0 :(得分:0)
我明白了......这里有一个额外的括号:
var availableTags = [ <?php echo json_encode($dname_list); ?> ];
显然,“echo json_encode($ dname_list)”PHP语句产生了一个额外的括号,它被JQuery Autocomplete解释为null,反过来又没有返回任何值。修复程序正在删除额外的括号:
var availableTags = <?php echo json_encode($dname_list); ?>;
感谢所有看过的人。此外, 重要 记住 如果您遇到挫折或代码挑战,请继续!不要放弃!你会找到一个解决方案!
