在 IE 11 上使用 jquery 时背景图像不会更改

Question

亲爱的，我试图在单击时使用jquery更改div背景图像，如下面的代码所示，它可以在除IE以外的所有浏览器上运行.....请帮忙

<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>

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JavaScript方法，

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