如何添加一個文件中去除這裏按鈕一樣簡單刪除一個去除按鈕點擊多個文件上傳文件排隊這樣當使用HTML5文件輸入
之所以我不是使用免費的文件上傳插件與OOB插件，因爲我的客戶需求是出於安全目的，他們需要簡單的上傳用戶界面，沒有任何複雜的插件。
$(function() {
var dropZoneId = "drop-zone";
var buttonId = "clickHere";
var mouseOverClass = "mouse-over";
var dropZone = $("#" + dropZoneId);
var ooleft = dropZone.offset().left;
var ooright = dropZone.outerWidth() + ooleft;
var ootop = dropZone.offset().top;
var oobottom = dropZone.outerHeight() + ootop;
var inputFile = dropZone.find("input");
document.getElementById(dropZoneId).addEventListener("dragover", function(e) {
e.preventDefault();
e.stopPropagation();
dropZone.addClass(mouseOverClass);
var x = e.pageX;
var y = e.pageY;
if (!(x < ooleft || x > ooright || y < ootop || y > oobottom)) {
inputFile.offset({
top: y - 15,
left: x - 100
});
} else {
inputFile.offset({
top: -400,
left: -400
});
}
}, true);
if (buttonId != "") {
var clickZone = $("#" + buttonId);
var oleft = clickZone.offset().left;
var oright = clickZone.outerWidth() + oleft;
var otop = clickZone.offset().top;
var obottom = clickZone.outerHeight() + otop;
$("#" + buttonId).mousemove(function(e) {
var x = e.pageX;
var y = e.pageY;
if (!(x < oleft || x > oright || y < otop || y > obottom)) {
inputFile.offset({
top: y - 15,
left: x - 160
});
} else {
inputFile.offset({
top: -400,
left: -400
});
}
});
}
document.getElementById(dropZoneId).addEventListener("drop", function(e) {
$("#" + dropZoneId).removeClass(mouseOverClass);
}, true);
inputFile.on('change', function(e) {
$('#filename').html("");
var fileNum = this.files.length,
initial = 0,
counter = 0;
for (initial; initial < fileNum; initial++) {
counter = counter + 1;
$('#filename').append('<span class="fa-stack fa-lg"><i class="fa fa-file fa-stack-1x "></i><strong class="fa-stack-1x" style="color:#FFF; font-size:12px; margin-top:2px;">' + counter + '</strong></span> ' + this.files[initial].name + ' <span class="fa fa-times-circle fa-lg closeBtn" title="remove"></span><br>');
