通過滾動頁面上的任何位置滾動溢出的div

Question

我想通過在頁面上的任何位置滾動來觸發帶有溢出內容的div的滾動，而不僅僅是移動鼠標並在div中單擊。 此外，我想隱藏div的滾動條，只有頁面的滾動條可見。

優選地，解決方案將基於CSS，但JS解決方案也將起作用。

這是我的jsfiddle，它演示了這個問題： http ： //jsfiddle.net/trpeters1/RMZsX/8/

我在這里復制代碼，但在那里我放了一堆填充文本來觸發滾動條。

但是對於你的參考，我想在滾動頁面時滾動的內部div的名稱有一個id="scrollMeToo" 。

Answer 1

 var curScroll = 0; $(window).bind('mousewheel DOMMouseScroll', function(e){ var evt = window.event || e; var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta; if(delta < 0) { //scroll down curScroll += 10; } else { //scroll up curScroll -= 10; } $('#scrollMeToo').scrollTop(curScroll); return true; }); 

 #scrollMeToo { height: 200px; width:150px; overflow: auto; position: relative; overflow-y: hidden; }

這應該做你需要的，如果你不想滾動文檔，只需改變return true; return false; 。

非jQuery方法：

 var curScroll = 0; function controlScroll (e) { var evt = window.event || e; var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta; if(delta < 0) { //scroll down curScroll += 10; } else { //scroll up curScroll -= 10; } document.getElementById('scrollMeToo').scrollTop = curScroll; }; if (document.attachEvent) {//if IE (and Opera depending on user setting) document.attachEvent("onmousewheel", controlScroll) } else if (document.addEventListener) { //WC3 browsers document.addEventListener("mousewheel", controlScroll, false) } 

 #scrollMeToo { height: 200px; width:150px; overflow: auto; position: relative; overflow-y: hidden; }

要更改滾動速度，只需修改此塊以滿足您的需要：

if(delta < 0) {
    //scroll down
    curScroll += 10;
}
else {
    //scroll up
    curScroll -= 10;
}

只需將10值更改為您需要的任何值即可。

更新：

var curScroll = 0;

$(window).on('mousewheel DOMMouseScroll', 'body', function(e){
    var evt = window.event || e;
    var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta;
    var loc = $('#scrollMeToo').scrollTop() + $('#scrollMeToo').innerHeight();
    var height = $('#scrollMeToo')[0].scrollHeight - 10;
    var height2 = $('#scrollMeToo')[0].scrollHeight - $('#scrollMeToo').innerHeight();
    if(delta < 0) {
        //scroll down
        if (curScroll < height2) {
            curScroll += 10;
        }
    }
    else {
        //scroll up
        if (curScroll > 0) {
            curScroll -= 10;
        }
    }
    if (loc >= height && !$('#scrollMeToo').hasClass('appended')) {
        var moreContent ='<a href="google.com">a link</a>';
        $('#scrollMeToo').append(moreContent);
        $('#scrollMeToo').addClass('appended');
        console.log('appended');
    }
    $('#scrollMeToo').scrollTop(curScroll);
    return true;
}); 

根據您所描述的內容，此修改應符合您的需求。 我也稍微修改了一些常規修復功能。

內容將出現在到達div的底部之前 ，只會出現一次。

Answer 2

你可以設置overflow：hidden for div。並設置css來取消選擇div內容。

 var clicking = false;
 var position;
 var scrollpos;
$(window).mousedown(function(e){
    clicking=true;
    position = e.pageY;
});
$(window).mouseup(function(){
      clicking = false;
})
$(window).mousemove(function(e){
      if(clicking == false) 
            return;
      scrollpos=$('#scrollMeToo').scrollTop();
      $('#scrollMeToo').scrollTop(scrollpos + (e.pageY-position)) ;
})
