我已经在 JQuery 和 html5 中实现了拖放功能,它在 chrome 中运行良好,但在 Firefox 中运行良好,下面是我的代码,我在其中警告丢弃图像的 id,它在 Firefox 中显示为未定义,下面是我的代码,请帮助。jsfiddle:http: //jsfiddle.net/rajutikale/2R6p8/
看法:
<!-- dragable image -->
<a href="#?w=976" rel="popup1" id="<?=$album['album_id'].'-'.$data->content_id?>" class="poplight album_photos"><img id="<?=$album['album_id'].'-'.$data->content_id?>" draggable="true" ondragstart="drag(event)" ondragover="allowDrop(event)" alt="" src="<?=$imagePath?>"></a>
<input type="hidden" id="<?='wall'.$data->content_id?>" value="<?=$data->wall_id?>" />
<input type="hidden" id="<?='type'.$data->content_id?>" value="<?=$data->content_type?>" />
<input type="hidden" id="<?='user'.$data->content_id?>" value="<?=$_SESSION['user_type']?>" />
<!-- dropable area -->
<div class="" style="z-index: 1; position:fixed; right:124px; top:60px" id="div1" ondrop="drop(event);;" ondragover="allowDrop(event);"> <a href="#"><img id="dropzon_image"src="<?php echo IMAGE_PATH_HTTP?>babbler_btn.jpg" alt="" border="0" style="cursor: pointer; cursor: hand; "/></a>
<div id="overlay" style="display:none;z-index: 2; position:fixed; right:0px; top:32px; cursor: pointer;border-color: blueviolet;">
<img id="drop_image" src="<?php echo IMAGE_PATH_HTTP?>drop_image.jpg" alt="" border="1" style="cursor: pointer; cursor: hand; " />
</div>
</div>
JS:
function allowDrop(ev) {
ev.preventDefault();
}
function drag(ev) {
ev.dataTransfer.setData("Text", ev.target.id);
$("#div1").find("#overlay").slideDown();
setTimeout(function () {
$("#overlay").hide();
}, 4000);
}
function drop(ev) {
var id = ev.dataTransfer.getData("Text"); /*implimented solution*/
alert(id);
ev.preventDefault();
var action = 'download';
var wall_id = '62';
var stat = 'Album';
var cnt = '0';
var user_type = 'R';
var status = do_download(action, wall_id, stat, cnt, user_type);
$("#overlay").hide();
// ev.target.appendChild(document.getElementById(data));
}
