function OpenDiv(_Dw,_Dh,_Desc) {
text1="好天气？？？"
text2="好麻烦啊？？"
改成
var text1, text2
text1="好天气？？？"
text2="好麻烦啊？？"
function OpenDiv(_Dw,_Dh,_Desc) {
因为你第一次执行时，text1和text2跟本没有给赋值。
当第一次点后才赋的值。以后再点当然显示正常了。
js实现点击输入用户名或密码的文本框在旁边弹出提示语 你可以使用formValidator.js，专门做表单验证的，效果如下：用法很简单，引用formValidator.js的核心类库，然后初始化$.formValidator.initConfig({formid: main ,debug:false,submitOnce : true})然后对要做校验的文本框编写校验代码$( #employeeNo ).formValidator({onshow : 输入范围为1到10个字符 ,在后面对应的显示提示语formValidator.js这个网上有很多实例和教程，很简单的(function (document) {var ttel = document.createElement('span')
ttel.style.position = 'absolute'
ttel.style.boder = '1px solid #e1dec9'
ttel.style.backgroundColor = '#eae9e3'
ttel.style.left = '0px'
ttel.style.top = '0px'
ttel.style.fontSize = '8pt'
ttel.style.padding = '2px 4px 2px 4px'
ttel.style.zIndex = 9999999
document.body.appendChild(ttel)
function showTooltip(e) {
console.log(e)
ttel.innerHTML = this.innerText || this.textContent || this.value
ttel.style.left = (e.pageX + 10) + 'px'
ttel.style.top = (e.pageY + 10) + 'px'
ttel.style.display = 'block'
return false
}
function hideTooltip(e) {
ttel.style.display = 'none'
ttel.innerHTML = ''
return false
}
