所以我有这个JS程序: http://codepen.io/anon/pen/avgQVa
$('.divider').draggable({
axis: 'x',
drag: function(e, ui) {
$('.right').width(100 - ui.position.left);
$('.yellow').css('right', ui.position.left);
}
});
我可以通过向右移动灰色分隔线来显示红色矩形,但每当我进入此块时,我需要使用此分隔符跟随鼠标。我该怎么做?
答案 0 :(得分:4)
// Handle the mouse move event on the parent div
$( "div:first" ).mousemove(function(e) {
// calculate the mouse position relative to the div element position on the page
var x = e.pageX - $(this).offset().left;
$('.divider').css('left', x);
$('.left').css('width', x);
});
为了使它工作,我也必须调整CSS:
.left {
left: 0px;
/* This makes the left div render "above" the others, so when we change its width it shows up */
z-index: 1;
}
