在 IE 11 上使用 jquery 时背景图像没有改变

Question

亲爱的们，我正在尝试使用 jquery 更改 div 背景图像，如下面的代码所示，它在除 IE 之外的所有浏览器上都可以工作......请帮助

<div id="section1" class="section111">
        <div class="container">
            <div style="width: 100%; z-index: 999999999;" class="ServicesTitle">
                <p class="Main_TitaleServices">SERVICES & SOLUTIONS</p>
                <p class="slogan">Full Solutions for a Perfect Business   </p>
            </div>
            <div id="title-underline" style="margin-bottom: -30px;">
                <img src="../../App_Themes/ThemeEn/Images/title-underline.png">
            </div>
            <div class="firstrow">
                <div class="col-lg-3 divServices ">
                </div>
                </div>

        </div>
    </div>

这是脚本

<script>
$(function () {
$("#WebsiteDevelopment").click(function () {
    $("#section1").css("background-image", "url(/App_Themes/ThemeEn/Images/webdevelopment.jpg !important")
    /

});
$("#btnWebsiteDevelopment").click(function () {


    $("#section1").css("background-image", "url(/App_Themes/ThemeEn/Images/section1bg.png")

});
});
</script>

Answer 1

尝试设置 background 而不是 background-image。

<script>
$(function () {
$("#WebsiteDevelopment").click(function () {
    $("#section1").css("background", "url(/App_Themes/ThemeEn/Images/webdevelopment.jpg !important")
    /

});
$("#btnWebsiteDevelopment").click(function () {


    $("#section1").css("background", "url(/App_Themes/ThemeEn/Images/section1bg.png")

});
});
</script>

或者使用纯粹的javascript方法，

document.getElementById('section1').backgroundImage = "url('url(/App_Themes/ThemeEn/Images/webdevelopment.jpg !important')";
