JS Custom Modify check box single box style, clear check box the default style of radio box

Before doing the project, also encountered the need to follow the design draft <input type="checkbox"> and <input type="radio"> the default style to modify, but found that there is no way to reset the effect, previously used-webkit-appearance method, but this is only in the WebKit kernel browser in effect, Firefox does not take effect.
So I wrote a JS, with Li to simulate the check box and the effect of the radio box, very simple, 7 lines on the line.

Knowledge points involved: Custom attributes to store the click state and the original class name

HTML content:

<DivId="Box" ><P> your favorite Sport</P><Ul><Li> Mountain Climbing</Li><Li> Bike</Li><Li> Swimming</Li><Liclass= ' Hong ' > Basketball </li> <li class=< Span class= "Hljs-value" > ' Hong ' > Soccer </li> <li> badminton </ li> <li> Jump Rope </li> < li> run </li> </ul></ DIV>             

JS content:

var aLi = Document.queryselectorall (' #box ul Li ');/* Get all of the LI, if you want to use the class, can be written as Document.queryselectorall ('. class ') */for (var i=0;i<ali.length;i++) {Ali[i].ifcheck =False/* The custom attribute is used to indicate that there is no selection, initialization set to FALSE, unchecked */ali[i].nowclass = Ali[i].classname;/* Custom attributes are used to store the original classname, such as the class name in the HTML content, Hong, so that after adding the class name on the back, it will not cause the original class name to be overwritten directly */Ali[i].onclick =function() {if (this.ifcheck) {/ * When the current Li is clicked, if Ifcheck is already selected */ this.classname =  This.nowclass /* makes the current click of the Li's class name equal to the original name, which means to remove the selected on class name */} else{ This.classname + = ' on ' / * If unchecked, add on to indicate that the selected */}/ * can be written as a three-mesh style this.classname = this.ifcheck?this.nowclass:this.classname+ ' on ';  This.ifcheck =! This.ifcheck; / * Start unchecked, click to select, or vice versa, so you want to give Ifcheck properties to counter */};};            

CSS style:

#box{Width600px;Margin50px Auto;}#boxP{Font-size:14px;Font-weight:BoldBorder-bottom:1px dashed#000;Line-height:30px;}#boxUl{Margin-top:10px;OverflowHidden}#boxUlLi{Width67px;Height20px;FloatLeftBackground-image:URL (images/ck.png);/* Background image when not selected */Background-repeat:No-repeat;Font-size:12px;Line-height:20px;Text-indent:30px;margin-right:8px; cursor:pointer;}  #box ul li.on{background-image: url (images/cked.jpg); /* selected time background map */} #box ul li.hong{ Span class= "Hljs-rule" >color:red;}
