I'm using ASP.NET VB, and I've implemented a top scrollbar that simulates the default bottom scrollbar. For some reason... when I resize the window, the top scrollbar stops working if the size goes below 90%... it continues to work as soon as the size goes back to 90% or above... I can't find a solution or any help...
I tried limiting the width to 90% of the width which still worked, but it didn't work... It seems that resize operations less than 90% are the only cause of the problem... not the width itself... However, I could be wrong...
This is the code:
<script type="text/javascript" src="/Scripts/jquery-3.6.0.min.js"></script>
<script type="text/javascript">
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
TopScrollBar();
});
$(document).ready(function () {
TopScrollBar();
});
$(window).resize(function () {
TopScrollBar();
});
function TopScrollBar() {
// 将divWidth的宽度设置为GridView1的宽度
$('#divWidth').width($('#GridView1').width());
// 将divScroll的滚动与GridContainer同步
$("#divScroll").on('scroll', function () {
$("#GridContainer").scrollLeft($(this).scrollLeft());
});
// 将GridContainer的滚动与divScroll同步
$("#GridContainer").on('scroll', function () {
$("#divScroll").scrollLeft($(this).scrollLeft());
});
}
</script>
<div id="divScroll" style="overflow-x: scroll; overflow-y: hidden; height: 20px;"
<div id="divWidth"></div>
</div>
<div id="GridContainer" style="overflow-x: scroll;">
<asp:GridView ID="GridView1" runat="server" CssClass="gridviewStyle" ClientIDMode="Static">
</asp:GridView>
</div>
CSS:
.gridviewStyle {
width: 100%;
border-collapse: collapse;
font-family: Arial, sans-serif;
}
I'm not sure if this is your only problem, but generally you need to use off before using on.
You are adding a new event listener but not removing the old one.
Try this:
function TopScrollBar() { // 设置divWidth的宽度与GridView1相同 $('#divWidth').width($('#GridView1').width()); // 将divScroll的滚动与GridContainer同步 $("#divScroll").off('scroll').on('scroll', function () { $("#GridContainer").scrollLeft($(this).scrollLeft()); }); // 将GridContainer的滚动与divScroll同步 $("#GridContainer").off('scroll').on('scroll', function () { $("#divScroll").scrollLeft($(this).scrollLeft()); }); }
