问题描述
我正在尝试在ajax响应中执行脚本，但似乎找不到任何方法来执行此操作.我的脚本加载在html-head标记中，我也有一个id为"browsemusic"的div，我的ajax响应进入该div.
I am trying to execute a script in an ajax response and can't seem to find any ways to do that. My scripts are loaded in the html - head tag, i also have a div with the id="browsemusic" where my ajax response goes to.
生成页面的我的php文件:
my php file which generates the page:
include('dbcon.php');
if(isset($_REQUEST['all']) && $_REQUEST['all'] != ''){
//===============================Button "ALL"====================================
unset($_REQUEST['kw']);
unset($_REQUEST['genre']);
$query = "select * from music";
$result = mysqli_query($link, $query) or die (mysqli_error());
echo '<ul id="sortable1" class="connected">';
while($info = mysqli_fetch_array( $result )){
echo '<li><div class="ui360"><button type="button" class="addtoplaylist" >Add</button><a href="' . $info['path'] . '"> '.$info['artist'].' - '.$info['title'].' ('.$info['album'].') '.'</a></div><hr /></li>';
};
echo '</ul>';
}elseif (isset($_REQUEST['kw']) && $_REQUEST['kw'] != ''){
//============================= Search for music ================================
$kws = $_REQUEST['kw'];
$kws = mysqli_real_escape_string($link, $kws);
$query = "select * from music where title like '%".$kws."%' or artist like '%".$kws."%'";
$result = mysqli_query($link, $query) or die (mysqli_error($link));
echo '<ul id="sortable1" class="connected">';
while($info = mysqli_fetch_array( $result )){
echo '<li><div class="ui360"><button type="button" class="addtoplaylist" >Add</button><a href="' . $info['path'] . '"> '.$info['artist'].' - '.$info['title'].' ('.$info['album'].') '.'</a></div><hr /></li>';
};
echo '</ul>';
}elseif(isset($_REQUEST['genre']) && $_REQUEST['genre'] != ''){
//=====================================Browse By Genre ===========================================
$genre = $_REQUEST['genre'];
$genre = mysqli_real_escape_string($link, $genre);
$gquery = "select music_id from musicgenre where genre_id = '$genre'";
$results = mysqli_query($link, $gquery) or die (mysqli_error($link));
$music=array();
while($id_result = mysqli_fetch_array($results)){
$music[] = $id_result['music_id'];
};
echo '<ul id="sortable1" class="connected">';
foreach($music as $song){
$query = "select * from music where music_id = '$song'";
$result = mysqli_query($link, $query) or die (mysqli_error());;
while($info = mysqli_fetch_array($result)){
echo '<li><div class="ui360"><button type="button" class="addtoplaylist" >Add</button><a href="' . $info['path'] . '"> '.$info['artist'].' - '.$info['title'].' ('.$info['album'].') '.'</a></div><hr /></li>';
};
};
echo '</ul>';
}else{
// ================================ Default =========================================
$query = "select * from music";
$result = mysqli_query($link, $query) or die (mysqli_error());
echo '<ul id="sortable1" class="connected">';
while($info = mysqli_fetch_array( $result )){
echo '<li><div class="ui360"><button type="button" class="addtoplaylist" >Add</button><a href="' . $info['path'] . '"> '.$info['artist'].' - '.$info['title'].' ('.$info['album'].') '.'</a></div><hr /></li>';
};
echo '</ul>';
};
和我的ajax文件:
$(document).ready(function(){
$(".all").click(function()
{
var all = $(this).attr("id");
if(all != '')
{
$.ajax
({
type: "POST",
url: "php/searchbrowselist.php",
data: "all="+ all,
success: function(option)
{
var $this = $("#browsemusic")
$this.html(option);
function loadjscssfile(filename, filetype){
if (filetype=="js"){ //if filename is a external JavaScript file
var fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript")
fileref.setAttribute("src", filename)
}
else if (filetype=="css"){ //if filename is an external CSS file
var fileref=document.createElement("link")
fileref.setAttribute("rel", "stylesheet")
fileref.setAttribute("type", "text/css")
fileref.setAttribute("href", filename)
}
if (typeof fileref!="undefined")
document.getElementsByTagName("head")[0].appendChild(fileref)
}
loadjscssfile("js/soundmanager2.js", "js") //dynamically load and add this .js file
loadjscssfile("js/360player.js", "js")
$('#sortable1, #sortable2').sortable({
connectWith: ".connected"
}).disableSelection();
}
});
}
return true;
});
});
loadjscssfile()函数是我发现这种工作的唯一方法.问题是，如果我单击另一个调用相同文件的流派(或另一个具有相似文件且具有相同功能的按钮)，它将停止工作.因此，它只能在第一次使用.
the loadjscssfile() function is the only way i found that kind of works. The problem is that if i click on another genre which calls the same file, (or another button that has a similar file with the same function in it) it stops working. So it works only the first time.
推荐答案
解决了，我不得不在我的ajax响应中重新启动脚本. (soundmanager2有一个reboot()函数)，所以ajax文件现在是:
solved, i had to reboot() the script in my ajax response. (there is a reboot() function for soundmanager2), so the ajax file is now:
$(document).ready(function(){
$(".all").click(function()
{
var all = $(this).attr("id");
if(all != '')
{
$.ajax
({
type: "POST",
url: "php/searchbrowselist.php",
data: "all="+ all,
success: function(option)
{
soundManager.reboot();
$("#browsemusic").html(option);
$('#sortable1, #sortable2').sortable({
connectWith: ".connected"
}).disableSelection();
}
});
}
return false;
});
});
