想要用JAVASCRIPT实现文本框跟随鼠标的移动的效果
盼高手出现
------解决方案--------------------------------------------------------
是指拖拽效果吗? 去下yahoo的yui看一下吧...不想自己写js..也可以直接使用
------解决方案--------------------------------------------------------
你关键要搞清楚什么时候才停止跟随鼠标移动停止？
你的代码的问题是onmouseout估计没有执行到
------解决方案--------------------------------------------------------
将textbox设为绝对定位.
document.getElementById( "TextBox1 ").style.position= "absolute "
------解决方案--------------------------------------------------------
这样即可
