二、实现


1、效果：点击“设置”的图标打开设置内容框，点击其他地方关闭设置内容框。


JavaScript直播评论发弹幕切图功能点集合效果代码







1.1、点击“设置”的图标打开设置内容框，点击其他地方关闭设置内容框。


第一步：重复点击“设置”图标，内容框显示隐藏交替。





$(".btn-set").click(function(evt){
$(".setform").toggle();
//evt.stopPropagation"htmlcode">



$(".tabcon").click(function(){
if($(".setform").is(":visible")){
$(".setform").hide();
}
});





此时会有问题，点击“设置图标”时显示不出来内容框。因为事件会冒泡，点击.btn-set后首先显示内容框，然后事件会冒泡到.tabcon的父元素，父元素绑定了事件让显示的内容框隐藏。解决方案就是阻止事件冒泡。即把第一步中的注释取消。





$(".btn-set").click(function(evt){
$(".setform").toggle();
evt.stopPropagation"text-align: center">JavaScript直播评论发弹幕切图功能点集合效果代码


2.1实现html如下





<div class="setform">
<ul class="dm-config cf">
<li class="dmopacity">
<span class="dm-setname">弹幕显示设置</span>
<div class="dragbar" style="position: relative;">
<span class="progress"></span>
<span class="icon" style="position: absolute;"></span>
</div>
<span class="percent">50%</span>
</li>
<li>
<span class="dm-setname">我的弹幕设置</span>
<div class="rgb-set cf">
<span>颜色</span>
<span class="rgb">#ffffff</span>
<span class="color" style="background:#ffffff"></span>
</div>
<div class="takecolor cf">
<a href="javascript:;" data-color="ff0000" style="background:#ff0000;"></a>
<a href="javascript:;" data-color="3399ff" style="background:#3399ff;"></a>
<a href="javascript:;" data-color="00fcff" style="background:#00fcff;"></a>
<a href="javascript:;" data-color="ff9900" style="background:#ff9900;"></a>
<a href="javascript:;" data-color="00ff12" style="background:#00ff12;"></a>
<a href="javascript:;" data-color="fff100" style="background:#fff100;"></a>
<a href="javascript:;" data-color="c8b33c" style="background:#c8b33c;"></a>
<a href="javascript:;" data-color="ff0096" style="background:#ff0096;"></a>
<a href="javascript:;" data-color="8600ff" style="background:#8600ff;"></a>
<a href="javascript:;" data-color="3399ff" style="background:#3399ff;"></a>
</div>
</li>
</ul>
</div>





2.2实现css如下





/*弹幕颜色*/
.setform {
z-index:99;
color: #999;
background: #252525;
border: 1px solid #424242;
width: 240px;
padding: 12px 22px 18px 18px;
}
.dm-config {
margin: 18px 0 0 0;
display: block
}
.dm-config li {
height: 90px
}
.dm-setname {
font-size: 14px;
color:#dedede;
font-weight: bold;
margin-bottom:20px;
display: block
}
.rgb-set {
height: 22px
}
.rgb-set span {
float: left;
display: inline;
color:#999;
}
.rgb {
width: 50px;
height: 18px;
border: 1px solid #d3d3d3;
line-height: 18px;
margin-left: 5px;
color: #424242;
padding: 0 0 0 5px
}
.color {
width: 20px;
height: 20px;
border: 1px solid #d3d3d3;
margin: -1px 0 0 2px
}
.takecolor {
width: 80px;
margin: 5px 0 0 30px
}
.takecolor a {
display: block;
width: 16px;
height: 16px;
float: left
}
.dmopacity {
float: right;
border-left: 1px solid #d3d3d3;
padding-left: 22px
}
.dragbar {
width: 85px;
height: 10px;
background: #d3d3d3;
position: relative;
margin-bottom: 10px;
cursor: default
}
.dragbar .progress {
width: 50%;
position: absolute;
height: 10px;
top: 0;
left: 0;
background: #39f
}
.dragbar .icon {
width: 4px;
height: 16px;
position: absolute;
top: -3px;
left: 50%;
background: #007cf7
}
.percent {
width: 85px;
text-align: center;
display: block;
color: #39f
}





3、进度条百分比实现





<script>
dragbar(85);
function dragbar( barwidth){
//var $box = $('.dragbar');
var $bg = $('.dragbar');
var $bgcolor = $('.progress');
var $btn = $('.icon');
var $text = $('.percent');
var statu = false;
var ox = 0;
var lx = 0;
var left = 0;
var bgleft = 0;
$btn.mousedown(function(e) {
lx = $btn.offset().left; //距离浏览器左边的距离
ox = e.pageX - left;
statu = true;
});
$(document).mouseup(function() {
statu = false;
});
$bg.mousemove(function(e) {
if (statu) {
left = e.pageX - ox;
if (left < 0) {
left = 0;
}
if (left > barwidth) {
left = barwidth;
}
$btn.css('left', left);
$bgcolor.width(left);
$text.html(parseInt(left / barwidth*100) + '%');
}
});
$bg.click(function(e) {
if (!statu) {
bgleft = $bg.offset().left;
left = e.pageX - bgleft;
if (left < 0) {
left = 0;
}
if (left > barwidth) {
left = barwidth;
}
$btn.css('left', left);
$bgcolor.stop().animate({
width: left
}, barwidth);
$text.html(parseInt(left / barwidth*100) + '%');
}
});
}
</script>
