200多个js技巧代码(一)
从CSDN上整理到的200多个js技巧，留着方便以后随时查阅，O(∩_∩)O哈哈~
1.文本框焦点问题
onBlur:当失去输入焦点后产生该事件
onFocus:当输入获得焦点后，产生该文件
Onchange:当文字值改变时，产生该事件
Onselect:当文字加亮后，产生该文件<input type="text" value="mm" onfocus="if(value=='mm) {value=''}" onblur="if
(value=='') {value='mm'}">点击时文字消失，失去焦点时文字再出现

document.form1.elements[i].disabled=!document.form1.elements[i].disabled;
