(1)获取元素坐标
- var $self=$(imgSelf);
- var offset2=$self.offset();
- var left=Number(offset2.left)+20;
(2)获取窗口大小
- //Cross browser gets the size of Visual area window,Have nothing to do with scroll bars
- var getInner=(function() {
- // alert(typeof window.innerWidth !== 'undefined');
- if (typeof window.innerWidth !== 'undefined') {//Notice:'undefined' is right
- return function(){
- return {
- width : window.innerWidth,
- height : window.innerHeight
- }
- }
- } else {
- return function(){
- return {
- width : document.documentElement.clientWidth,
- height : document.documentElement.clientHeight
- }
- }
- }
- })();
- var delta=left+50-getInner().width;
(3)动态增加节点
在后面增加兄弟节点
- $next.after('<div id="answer_'+id+'" ></div>');
增加子节点:
- $('body div.draft').append(html);
