老濕有個問題一直困擾我：

正常是這樣：
window.onload=function?()?{
????var?myName?=?document.getElementById("tddd");
????myName.onmouseover?=?function?()?{
????????startMove();
????}
}
????var?time?=?null;

????function?startMove()?{
????????clearInterval(time);
????????var?myName?=?document.getElementById("tddd");
????????setInterval(function?()?{
????????????if?(myName.offsetLeft?==?150)?{
????????????????clearInterval(time);
????????????}?else?{
????????????????myName.style.left?=?myName.offsetLeft?+?1?+?"px";
????????????}
????????},?30)
????}
????

第二種第二個函數(shù)是在第一個函數(shù)里面也就是startMove執(zhí)行函數(shù)在鼠標事件函數(shù)里面{}，可以執(zhí)行。????
window.onload=function?()?{
????var?myName?=?document.getElementById("tddd");
????myName.onmouseover?=?function?()?{
????????startMove();
????}

????var?time?=?null;

????function?startMove()?{
????????clearInterval(time);
????????var?myName?=?document.getElementById("tddd");
????????setInterval(function?()?{
????????????if?(myName.offsetLeft?==?150)?{
????????????????clearInterval(time);
????????????}?else?{
????????????????myName.style.left?=?myName.offsetLeft?+?1?+?"px";
????????????}
????????},?30)
????}
????}
增加一個移開事件onmouseout之后，按照第二種，移開鼠標物體繼續(xù)向前運動。這個是怎么回事，老濕幫幫解釋下。。。。。。。。。。。。

移開是這樣：

window.onload=function?()?{
????var?myName?=?document.getElementById("tddd");
????myName.onmouseover?=?function?()?{
????????startMove();
????}
????myName.onmouseout?=?function?()?{
????????startMove1();
????}

????var?time?=?null;
????function?startMove()?{??????
????????clearInterval(time);
????????var?myName?=?document.getElementById("tddd");
????????setInterval(function?()?{
????????????if?(myName.offsetLeft?==?150)?{
????????????????clearInterval(time);
????????????}?else?{
????????????????myName.style.left?=?myName.offsetLeft?+1?+?"px";
????????????}
????????},?30)
????}
????function?startMove1()?{
????????clearInterval(time);
????????var?myName?=?document.getElementById("tddd");
????????setInterval(function?()?{
????????????if?(myName.offsetLeft?==?-20)?{
????????????????clearInterval(time);
????????????}?else?{
????????????????myName.style.left?=?myName.offsetLeft?-1?+?"px";
????????????}
????????},?30)
????}
}

結(jié)果是移開物體繼續(xù)向前走，
