Native JS implementation of DOM operation notes (draft collation)

Native JS implements a series of Dom operation references:

• Native JavaScript wrapper Dom Library
• Siblings: Native js-the implementation of-siblings method for finding adjacent elements
• Addclass,removeclass,hasclass,toggleclass: Native JS Add delete class
• Native JS Add Delete class

The code is as follows:

varDom = {        /** Function Description: Whether the matching element contains the specified class * @param el specified DOM element * @param className matches the class name **/Hasclass:function(el,classname) {returnEl.className.match (NewRegExp (' (\\s|^) ' + ClassName + ' (\\s|$) ')); },        /** Function Description: Adds class * @param el specified DOM element to the specified DOM element * @param className Added class name **/AddClass:function(el,classname) {if(! This. Hasclass (El,classname)) {El.classname+= " " +ClassName; }        returnel; },        /** Function Description: Remove class * @param el specified DOM element for specified DOM element * @param className removed class name **/Removeclass:function(el,classname) {if( This. Hasclass (El,classname)) {            varReg =NewRegExp (' (\\s|^) ' + ClassName + ' (\\s|$) '); El.classname= El.className.replace (Reg, ")        }        returnel; },        /** Function Description: Adds or removes the class * @param el specified DOM element for the specified DOM element * @parm className Add or remove class name **/Toggleclass:function(el,classname) {if( This. Hasclass (El,classname)) {             This. Removeclass (El,classname); }Else{             This. addclass (El,classname); }        returnel; },        /** Function Description: Gets the current element of the sibling node * @param el current DOM element **/Siblings:function(EL) {varmatched = [];//Storing sibling nodes        varn = (El.parentnode | |{}). firstchild;  for(; n; n =n.nextsibling) {            if(N.nodetype = = = 1 && n!==el)            {Matched.push (n); }        }        returnmatched; }};
