Web Front-endHTML TutorialHow to realize the report effect of dynamically displaying color blocks in Html
This time I will show you how to implement the report effect of dynamically displaying color blocks in Html. What are the things to note in Html?What are the practical cases? Let’s take a look. .
<style type="text/css">
*{
padding: 0;
margin: 0;
}
.tubiao,.jihua,.shiji,.riqi{
width: 100%;
overflow: hidden;
margin-top: 10px;
}
.left{
width: 10%;
float: left;
text-align: center;
height: 25px;
line-height: 25px;
}
.right{
width: 90%;
float: right;
height: 25px;
}
span {
width: 5%;
height: 100%;
text-align: center;
display: inline-block;
}
</style><body>
<div class="tubiao">
<div class="jihua">
<div class="left">计划</div>
<!--计划span存放的地方-->
<div class="right plan"></div>
</div>
<div class="shiji">
<div class="left">实际</div>
<!--实际span存放的地方-->
<div class="right act"></div>

var temp3="5/19-5/20-5/21-5/22-5/23-5/24-5/25-5/26-5/27-5/28";//综合日期
var temp=temp1+"~"+temp2+"~"+temp3;
var plan = document.getElementsByClassName("plan")[0];
var act = document.getElementsByClassName("act")[0];
var day = document.getElementsByClassName("day")[0];
var num = 20;//创建多少个格
load_first(temp);
//分割数据和添加色块操作
function load_first(temp){
var demo=temp.split("~");
var d1=demo[0].split("-");//计划耗时（块的单位宽度）数组
var d2=demo[1].split("-");////实际耗时（块的单位宽度）数组
var d3=demo[2].split("-");//综合日期数组
for(var i=0;i<d3.length;i++){

}
document.getElementById("day_id").style.marginLeft="-30px";

//新增颜色块,a为计划颜色块宽度，b为实际颜色块宽度
function add_span(a,b,i){
//创建span块

//定义随机底色
var spa = "rgba(" + rnd(0,255)+ "," + rnd(0,255)+ ","+ rnd(0,255)+ ","+ rnd(0.5,1) +")";//每一个颜色随机出来
if(i==0){

//clientWidth是对象看到的宽度（不含边线,即border）
