Question

我需要一个组件来改变带滑块的图像颜色。为此，我修改了Javascript代码，以便在滑块移动时更改原始图像顶部的不同彩色图像的不透明度。我还添加了一个调光功能，使用不透明度和黑色div使图像变暗。

它在Chrome和Firefox中运行良好。我不能为我的生活弄清楚如何让它在Internet Explorer中工作。我是Javascript的新手，所以它可能很明显，但有人可以提供帮助吗？！？

的Javascript

var slider = document.getElementById("myRange");
        var output = .5;
        var imageTrans = document.getElementById("cool");
        output.innerHTML = slider.value; // Display the default slider value

        // Update the current slider value (each time you drag the slider handle)
        slider.oninput = function() {
            output.innerHTML = this.value;
            imageTrans.style.opacity = slider.value;
        }

        var sliderDim = document.getElementById("myRangeDim");
        var outputDim = 0;
        var imageTransDim = document.getElementById("dimmer");
        outputDim.innerHTML = sliderDim.value; // Display the default slider value

        // Update the current slider value (each time you drag the slider handle)
        sliderDim.oninput = function() {
            outputDim.innerHTML = this.value;
            imageTransDim.style.opacity = sliderDim.value;
        }

谢谢！

对于旧的IE用户，您可能需要将附加javascript功能的事件更改为 - 从oninput更改为onchange或onmousemove。
