在下面的示例中，用户在滚动300px后会看到一个模态。 但我的问题是，如果我给div添加固定高度，它就不会触发。我希望它有一个固定的高度和它自己的滚动条。

这是参考代码，您可以根据需要对其进行修改 在if
中显示模态
// custom 'scrolldelta' event extends 'scroll' event
jQuery.event.special.scrolldelta = {
delegateType: "scroll",
bindType: "scroll",
handle: function (event) {
var handleObj = event.handleObj;
var targetData = jQuery.data(event.target);
var ret = null;
var elem = event.target;
var isDoc = elem === document;
var oldTop = targetData.top || 0;
var oldLeft = targetData.left || 0;
targetData.top = isDoc ? elem.documentElement.scrollTop + elem.body.scrollTop : elem.scrollTop;
targetData.left = isDoc ? elem.documentElement.scrollLeft + elem.body.scrollLeft : elem.scrollLeft;
event.scrollTopDelta = targetData.top - oldTop;
event.scrollTop = targetData.top;
event.scrollLeftDelta = targetData.left - oldLeft;
event.scrollLeft = targetData.left;
event.type = handleObj.origType;
ret = handleObj.handler.apply(this, arguments);
event.type = handleObj.type;
return ret;
}
};
// bind to custom 'scrolldelta' event
$(window).on('scrolldelta', function (e) {
var top = e.scrollTop;
var topDelta = e.scrollTopDelta;
var left = e.scrollLeft;
var leftDelta = e.scrollLeftDelta;
// do stuff with the above info; for now just display it to user
var feedbackText = 'scrollTop: ' + top.toString() + 'px (' + (topDelta >= 0 ? '+' : '') + topDelta.toString() + 'px), scrollLeft: ' + left.toString() + 'px (' + (leftDelta >= 0 ? '+' : '') + leftDelta.toString() + 'px)';
document.getElementById('feedback').innerHTML = feedbackText;
if(top >= 300){
alert("Show Modal");
//you can write modal show code here
}
});#content {
/* make window tall enough for vertical scroll */
height: 2000px;
/* make window wide enough for horizontal scroll */
width: 2000px;
/* visualization of scrollable content */
background-color: blue;
}
#feedback {
border:2px solid red;
padding: 4px;
color: black;
position: fixed;
top: 0;
height: 20px;
background-color: #fff;
font-family:'Segoe UI', 'Arial';
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='feedback'>scrollTop: 0px, scrollLeft: 0px</div>
<div id='content'></div>

这对我有用我使用了@ ruby的代码片段并相应地更改了我的代码
function displayModalForm () {
$('.list').scroll(function() {
wS = $(this).scrollTop();
if (wS > 300 && $("#searchModalForm").attr("displayed") === "false") {
$('#searchModalForm').modal('show');
$("#searchModalForm").attr("displayed", "true");
}
});
}
displayModalForm();
