本文介绍了一个简单的HTML表单，包含两个输入框用于搜索操作。通过JavaScript实现了输入框的焦点和鼠标悬停效果，改变边框颜色以提高用户体验。
<style>
input{border:#5656561pxsolid;height:20px;line-height:19px;vertical-align:middle;font-size:12px;color:#565656;}

functionfEvent(sType,oInput){
switch(sType){
case"focus":
oInput.isfocus=true;
case"mouseover":
oInput.style.borderColor='#f00';
break;
case"blur":
oInput.isfocus=false;
case"mouseout":
if(!oInput.isfocus){
oInput.style.borderColor='#565656';
}
break;
}
}
