我实现了多图像上传并正常工作。我的问题是我只想用一个按钮来实现它。单击时,将弹出浏览对话框并选择图像。我怎样才能做到这一点?
var counter = 0;
$(document).ready(function() {
// To add new input file
$('[id^=add_more]').click(function() {
$("#show" + this.id.replace(/\D/g, "")).append($("<div/>", {
id: 'filediv'
}).fadeIn('slow').append($("<input/>", {
name: 'theImage',
type: 'file',
id: 'file'
})));
});
$('body').on('change', '#file', function() {
if (this.files && this.files[0]) {
var ext = $( this).val().split('.').pop().toLowerCase();
if($.inArray(ext, ['gif','png','jpg','jpeg']) == -1) {
$('#file').val('');
$('#file').remove();
alert('Type Of File Is Not Valid!');
}else{
counter += 1;
$(this).before("<div id='abcd" + counter + "' class='abcd'><img id='previewimg" + counter + "' src=''/></div>");
var reader = new FileReader();
reader.onload = imageIsLoaded;
reader.readAsDataURL(this.files[0]);
$(this).hide();
$("#abcd" + counter).append($("<i/>", {
class: 'fa fa-times',
id: 'img',
top:0,
alt: 'delete'
}).click(function() {
$(this).parent().parent().remove();
}));
}
}
});
// Preview Img
function imageIsLoaded(e) {
$('#previewimg' + counter).attr('src', e.target.result);
}
});
