JQuery自动填充问题?

标签: php jquery css autocomplete jquery-ui-autocomplete

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">

</head>
<body>

<div class="ui-widget">
  <label for="tags">Tags: </label>
  <input id="tags">
</div>

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

<script type="text/javascript">
    $(function() {
        var availableTags = [ <?php echo json_encode($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;
    float: left;
    clear: left;
    width: 100%;
}
.ui-menu .ui-menu-item a {
    text-decoration:none;
    display:block;
    padding:.2em .4em;
    line-height:1.5;
    zoom:1;
}
.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); ?>;
