如何从容器中删除选定的图像？我想一次删除一张图片 我尝试过的所有操作都是在我双击图片时同时删除所有图片 这是一个 fiddle https://jsfiddle.net/4ezggt9h/8/

jQuery(function ($) {
    $('div').on('click', '.closeDiv', function () {
        $(this).prev().remove();
        $(this).remove();
        $('#upload-file').val("");
    });
    var fileDiv = document.getElementById("upload");
    var fileInput = document.getElementById("upload-file");

    fileInput.addEventListener("change", function (e) {

        var filesVAR = this.files;

        showThumbnail(filesVAR);

    }, false);



    function showThumbnail(files) {
        var file = files[0]
        var thumbnail = document.getElementById("thumbnail");
        var pDiv = document.createElement("div");
        var image = document.createElement("img");
        var div = document.createElement("div");


        pDiv.setAttribute('class', 'pDiv');
        thumbnail.appendChild(pDiv);


        image.setAttribute('class', 'imgKLIK5');
        pDiv.appendChild(image)

        div.innerHTML = "X";
        div.setAttribute('class', 'closeDiv');
        pDiv.appendChild(div)

        image.file = file;
        var reader = new FileReader()
        reader.onload = (function (aImg) {
            return function (e) {
                aImg.src = e.target.result;
            };
        }(image))
        var ret = reader.readAsDataURL(file);
        var canvas = document.createElement("canvas");
        ctx = canvas.getContext("2d");
        image.onload = function () {
            ctx.drawImage(image, 100, 100);
        }
    }
});

Answer 1

此代码适用于 jQuery < 1.7 .live()

为名为 deleteme 的添加图像添加额外的类

var $drop = jQuery("<div>", {
        class : "dragbal deleteme",
        style : "position: absolute; top: 100px; left: 100px;",

    });

在 deleteme 类上添加一个实时监听器，用于双击并执行删除操作

$(function () {
    $(".deleteme").live("dblclick", function () {
        console.log('clicked delete')
        $(this).remove();
    });
});

我想这就是你想要的
