Question

我在home.php中有一个上传文件表单。成功上传文件后home.php加载upload.php我有表格的地方，用户可以写出有关mp3文件的信息，如艺术家姓名等信息。我想通过jQuery实现自动完成脚本。但是当通过javascript代码加载时，自动完成功能不起作用，但是当我访问upload.php页面时它可以正常工作。可能是什么问题？

Home.php

<!DOCTYPE html>
<html>

<head>
    <meta charset="ISO-8859-6">
    <script src="src/script.js" type="text/javascript" charset="iso-8859-6"></script>
</head>

<body style="margin-top:-60px;">
    <form id="upload_form" enctype="multipart/form-data" method="post" action="upload.php">
        <div>
            <input class="ufile" type="file" name="ufile" id="ufile" accept="audio/*" onchange="loadFile(this)" />
            <input type="button" class="button" id="upload_button" value="ارفع ملف صوتي" onclick="inputCheck()" />
        </div>
    </form>
    <div style="padding:0px 10px 0px 10px;">
        <div id="upload_response"></div>
    </div>
</body>

的script.js

function uploadFinish(e) { // upload successfully finished
    var oUploadResponse = document.getElementById('upload_response');
    oUploadResponse.innerHTML = e.target.responseText;
    oUploadResponse.style.display = 'block';
    $("#upload").animate({
        height: '765px'
    }, 350);
    $('#errormessage').slideUp('fast');
}

Answer 1

您正在DOM元素准备好之前执行脚本。

你可以做几件不同的事情来解决它，例如：

将脚本加载到页面底部
将您的脚本移动到文档就绪事件中，以便DOM元素可用 $(document).ready(function() { -your script here- });

Answer 2

你可以使用ajax来使用自动完成型插件..

<style>

label._tags {
    padding:5px 10px;
    margin:0px;
    border:solid thin #ccc;
    border-radius:3px;
    display: inline-block;
}

label._tags span {
    padding:2px 10px;
    margin: 0px 10px;
    color:#FFF;
    border-radius:700px;
    font-family:"calibri",verdana,serif;
    background-color:teal;
}

</style>
<script type="text/javascript">



var request;
var tag=new Array();
function getXMLObject(){
    if(window.XMLHttpRequest){
        return(new XMLHttpRequest);
    }else if(window.ActiveXObject){
        return(new ActiveXObject("Microsoft.XMLHttp"));
    }else{
        return (null);
    }
}


function getCategory(){


    var address="Ajax_testing";
     request=getXMLObject();
     var data=document.getElementById("multitag").value;

     var nwadd=address+"?text="+data;


     request.onreadystatechange=showResultsubject;
     request.open("GET",nwadd,true);
     request.send();
}


function close()
{

     var y=document.getElementById("p");



    var myNode = document.getElementById("p");
        while (myNode.firstChild) {
         myNode.removeChild(myNode.firstChild);
        }
     y.setAttribute("style","dispaly:none;");




}

function removetag(id)
{

     var y=document.getElementById("l");

     var z=document.getElementById(id.substr(3));

     tag.pop();

         y.removeChild(z);






}
  function gettag(id){


     tag.push(id);
     var f="";

     for (var i=0;i<tag.length;i++)
     {

         var s="<label class='_tags' id='"+tag[i]+"'>"+tag[i]+"<span><a  id='tag"+tag[i]+"' onclick='removetag(this.id)'>X</a></span> </label>";

          f=f.concat(s);
     }

     document.getElementById("l").innerHTML=f;
    }






       <tr>
            <td>Keyword :

             </td>

            <td><input type="text" id="multitag"  name="multitag" onkeyup="getCategory()" onclick="close()">
            <div id="l">

            </div>



           <div id="p" style="display: none;z-index:11;" >

           </div> 
           </td> 
           </tr>
