[求助]关于JAVASCRIPT函数的参数意义
<img onmouseup="FP_swapImg(0,0,/*id*/'img1',/*url*/'Img/Homepage.jpg')" onmousedown="FP_swapImg(1,0,/*id*/'img1',/*url*/'Img/Homepage1.jpg')" id="img1" onmouseover="FP_swapImg(1,0,/*id*/'img1',/*url*/'Img/Homepage.jpg')" style="WIDTH: 100px; HEIGHT: 32px" onmouseout="FP_swapImg(0,0,/*id*/'img1',/*url*/'Img/homepage2.jpg')" height="32" alt="首页" src="" border="0" fp-title="首页" fp-style="fp-btn: Border Bottom 2; fp-font" Imghomepage2.jpwidth="100">
谁能帮我看一下“ FP_swapImg(0, 0, /*id*/'img1', /*url*/'Img/Homepage.jpg')" ” 这个JAVASCRIPT函数中这些参数的意义!!
