有人可以发现我的错误(自动填充文本框)吗?

标签: javascript php ajax

到目前为止,我有HTML:

<div id="box" style="width:400; height:400; margin-left:auto; margin-right:auto; margin-top:100;">
<h2>Enter a word</h2>
<input type="text" id="input" ></input>
</div>
<div id="suggest">
</div>

使用Javascript:

<script type ="text/javascript">
$(document).ready(function(){
$("#input").keyup(function(){
var input = $("#input").val();
$.ajax({
url: "PathToPHPFileThatConnectsToDatabaseAndRetreivesValues",
data: "input"+input,
success: function(msg){
alert(msg);
$("#suggest").html(msg);
}
});
});
});
</script>

PHP:

<?php

$dbh=mysql_connect ("localhost", "~", "~") or die ('I cannot connect to the database because: ' . mysql_error()); 
mysql_select_db ("~") or ("Database not found");

$input = $_REQUEST['input'];

$input = mysql_real_escape_string(trim($input));

    $sql = "SELECT * FROM ~ WHERE ~ LIKE '%".$input."%'";

    $data = mysql_query($sql);

    $arrcnt = -1;

    $dataArray = array();

    while ($temp = mysql_fetch_assoc($data)) 
        {
            foreach($temp as $key=>$val) {
                $temp[$key] = stripslashes($val);
                $arrcnt++;
        }
        $dataarray[$arrcnt] = $temp;
    }

    $list = "<ul style='width:100;height:auto;'>";

    foreach($dataArray as $val) {
        $list .= "<li>".$val['DesiredColumnContainingDesiredData']."</li>";
    }

    $list .= "</ul>";

    echo $list;



?>

现在,这些代码应该一起工作以使用id =&#34自动完成div;建议&#34;然后使用id =&#34填充文本字段;输入&#34;选中后......我会一直收到警告:<ul style='width:100;height:auto;'></ul>

更改像这样的ajax代码,

$.ajax({
url: "PathToPHPFileThatConnectsToDatabaseAndRetreivesValues",
data: {"input":input},
success: function(msg){
alert(msg);
$("#suggest").html(msg);
}
});

问题是因为在php中你的变量名称是不同的。您添加了$ dataarray而不是$ dataArray

此外还有ajax

您可以将数据作为字符串或对象传递

数据:{ “输入”:输入}

数据: “输入=” +输入

在ajax中添加类型:'POST'
