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>
</div>
<div class="riqi" id="day_id">
<!--日期存放的地方-->
<div class="right day"></div>
</div>
</div>
<script type="text/javascript">
var temp1="0-0.5-2-2-2-2-1-1";//计划耗时（块的单位宽度）
var temp2="1-1-2-1-2-0-0-0";//实际耗时（块的单位宽度）
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++){
time_span(d3[i]);
}
//alert("6:"+d1.length+"---"+"3:"+d2.length);
//alert("d3.length:"+d3.length);
for(var i=0;i<d1.length;i++){
add_span(d1[i],d2[i],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
var span1 = document.createElement("span");
var span2 = document.createElement("span");
//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){
span1.style.backgroundColor = "000000";
//clientWidth是对象看到的宽度（不含边线,即border）
span1.style.width = (plan.clientWidth/num*a) + "px";//计划的每一格的宽度
//插入节点span1至plan
plan.appendChild(span1);
span2.style.backgroundColor = "000000";
span2.style.width = (plan.clientWidth/num*b) + "px";//实际的每一格的宽度

}
}
//日期的数据插入
function time_span(time){

span.innerHTML = "" + time;

}
//随机函数
function rnd(min,max){
return Math.round(Math.random()*(max - min)+min);
}
function QueryData() {
