I implemented a following HTML <input> multiple Attribute
<input type="file" name="R" id="someattachId" multiple="multiple" style='display:none' />
I'm trying to remove specific item in it using following code
$('#someattachId')[0].files[fileId].remove();
but it can't remove it.
No, We can make it removable. I implemented this and it works definitely.
First you need to initialize this variables
var newImageObj = [];
var ImageNo = 0;
Then write this code on file input's change
$("#exampleInputFileProduct").change(function () {
var fileUpload = document.getElementById("exampleInputFileProduct");
//$("#mainImages").html('');
//$("#subImages").html('');
if (typeof (FileReader) != "undefined") {
//Here Check File Extension
var regex = /^([a-zA-Z0-9\s_\\.\-:])+(.jpg|.jpeg|.gif|.png)$/;
for (var i = 0; i < fileUpload.files.length; i++) {
var j = 0;
var file = fileUpload.files[i];
var NewFile = fileUpload.files[i];
//Here Check File Size 1MB = 1000000 Bytes
if (file.size < 2048000) {
if (regex.test(file.name.toLowerCase())) {
var reader = new FileReader();
reader.onload = function (e) {
if ($("#mainImages").find(".item").attr("id") == "FirstSlider") {
$("#mainImages").html('');
$("#subImages").html('');
$("#subImages").append("<div class='item active'></div>");
}
if ($("#mainImages").find(".item").hasClass("active")) {
$("#mainImages").append("<div class='item " + ImageNo + "_CClass\'><i class='fa fa-times customIcon' onclick='RemoveImage(\"" + ImageNo + "_CClass\",\"" + fileUpload.files[j].name.toLowerCase() + "\")'></i><img class='CImage' src='" + e.target.result + "' alt='' /></div>");
} else {
$("#mainImages").append("<div class='item active " + ImageNo + "_CClass'><i class='fa fa-times customIcon' onclick='RemoveImage(\"" + ImageNo + "_CClass\",\"" + fileUpload.files[j].name.toLowerCase() + "\")'></i><img class='CImage' src='" + e.target.result + "' alt='' /></div>");
}
//if ($("#subImages").find(".item").length == 0) {
// $("#subImages").append("<div class='item active'></div>");
//} else {
if (($("#subImages").find(".item").find("div").length / 5) >= $("#subImages").find(".item").length) {
$("#subImages").append("<div class='item'></div>");
}
//}
var append = 0;
$.each($("#subImages").find(".item"), function (p, pelement) {
if (append == 0) {
if ($(pelement).find("div").length != 5) {
var newID = $(pelement).find("div").length;
newID = newID;
$(pelement).append("<div onclick='LoadImage(\"" + ImageNo + "_CClass\")' data-slide-to='" + newID + "' class='thumb " + ImageNo + "_CClass'> <img src='" + e.target.result + "' alt=''></div>");
append = append + 1;
}
}
})
j = j + 1;
ImageNo = ImageNo + 1;
}
newImageObj.push(file);
reader.readAsDataURL(file);
}
}
}
} else {
alert("This browser does not support HTML5 FileReader.");
}
});
Then at last this 2 functions will help to do the rest
function LoadImage(objclass) {
$("#mainImages").find(".item").removeClass("active");
$("#mainImages").find("." + objclass + "").addClass("active");
}
function RemoveImage(objclass, ImageName) {
$.each(newImageObj, function (e, element) {
if ($(this)[0].name.toLowerCase().trim() == ImageName.trim()) {
newImageObj.pop(this);
}
});
$("#mainImages").find("." + objclass + "").remove();
$("#subImages").find(".item").find("." + objclass + "").remove();
if ($("#mainImages").find(".item").length == 0) {
$("#mainImages").append("<div class='item active'><i class='fa fa-times customIcon'></i><img class='CImage' src='/Content/img/DefaultProduct.gif' alt='' /></div>");
$("#subImages").append("<div class='item active'><div data-target='#carousel' data-slide-to='0' class='thumb'> <img src='/Content/img/DefaultProduct.gif' alt=''></div></div></div>");
} else {
$("#mainImages").find(".item").removeClass("active");
$("#mainImages").find(".item:first-child").addClass("active");
$("#subImages").find(".item").removeClass("active");
$("#subImages").find(".item:first-child").addClass("active");
}
}
At last when you submit your form than take the files from the array
validatedFilesin server side then
