我正在使用jquery-html5-uploader通过AJAX上传文件,我遇到了以下问题。上传文件时,正在调用* handleSuccess *函数 - 用于每个上传的文件。这给我带来了一个问题 - 当您点击图片链接时正在插入textarea。就我而言,对于每个文件,都插入了相同数量的链接。我怎样才能只调用一次函数,或删除所有创建的对象并只获取一个对象(或者基本上任何可以防止这种情况的对象)? 代码:
function img_upload(url) {
{
var fileTemplate = "<div role=\"id_image\" id=\"{{id}}\" class=\"clearfix fl slika_prv\" >";
fileTemplate += "<div class=\"preview\"></div>";
fileTemplate += "<div class=\"filename\">{{filename}}</div>";
fileTemplate += "<a href=\"" + url_tmp_delete + "\" class=\"image_delete_tmp\" role={{id}}>Obriši Sliku</a>";
fileTemplate += "</div>";
function slugify(text) {
text = text.replace(/[^-a-zA-Z0-9,&\s]+/ig, '');
text = text.replace(/-/gi, "_");
text = text.replace(/\s/gi, "-");
return text;
}
$("#dropbox").html5Uploader({
postUrl: url,
onClientLoadStart: function (e, file) {
var upload = $("#upload");
if (upload.is(":hidden")) {
upload.show();
}
upload.append(fileTemplate.replace(/{{id}}/g, slugify(file.name)).replace(/{{filename}}/g, file.name))
},
onClientLoad: function (e, file) {
$("#" + slugify(file.name))
.find(".preview")
.append("<img class=img_upload title=\"" + file.name + "\" src=\"" + e.target.result + "\" alt=\"\">");
},
onServerLoad: function (e, file) {
},
onSuccess : function(e, file, data) {
var id_slika = slugify(file.name)
upload_folder = $('#upload');
upload_folder.find('#' + id_slika).find('a').attr('data-id', data);
var img_delete = $('.image_delete_tmp');
handleSuccess(upload_folder);
delete_image(img_delete, 'tmp');
}
});
}
}
function handleSuccess() {
var upload_folder = $('#upload');
console.log(upload_folder.first());
upload_folder.on('click', 'img', function(e){
var $this = $(this),
text = $this.parent().parent().find('a').data('id'),
img = ('<img src="<?php echo IMG ?>pages/' + text + '" />');
$("#page_srb").insertAtCursor(img);
// element.remove();
return false;
});
}
这是我点击文件时获得的(这是3个文件):
<img src="http://localhost/pirot_opstina/public/img/pages/Digital_composite_spring_(9)37.jpg" />
<img src="http://localhost/pirot_opstina/public/img/pages/Digital_composite_spring_(9)37.jpg" />
<img src="http://localhost/pirot_opstina/public/img/pages/Digital_composite_spring_(9)37.jpg" />
答案 0 :(得分:0)
如果这个插件支持像onSuccessAll这样的东西会很容易......但是看起来不是这样......如果它只是显示一个图像,我会:
function handleSuccess() {
var upload_folder = $('#upload');
console.log(upload_folder.first());
upload_folder.on('click', 'img', function(e){
if ($(".onlyone").length < 1){
var $this = $(this),
text = $this.parent().parent().find('a').data('id'),
img = ('<img class="onlyone" src="<?php echo IMG ?>pages/' + text + '" />');
$("#page_srb").insertAtCursor(img);
// element.remove();
return false;
}
});
}
所以它检查是否已经有类onlyone
的元素,并且只有在没有它的情况下才会添加图像。但是,这意味着图像将从第一次上传而不是最后一次显示。
