JS control picture, such as scaling the scale of sample code

  This article is mainly on the JS control picture, such as proportional scaling sample code is introduced, the need for friends can come to the reference, I hope to help you.

The code is as follows: <script language= "JavaScript" > Function DrawImage (imgd,fitwidth,fitheight) {       var Image=new Image ();        IMAGE.SRC=IMGD.SRC;        if (image.width>0 && image.height>0) {           IF (image.width/image.height>= fitwidth/fitheight) {               if (image.width>fitwidth) {         &N Bsp         imgd.width=fitwidth;                    imgd.height= (image.height*fitwidth)/image.width;               ,                else{&nbs p;                  imgd.width=image.width;                    imgd.height=image.height;            &NBsp  }                       else{     &NB Sp         if (image.height>fitheight) {                 & nbsp Imgd.height=fitheight;                    imgd.width= (image.width*fitheight)/image.height;               ,                else{&nbs p;                  imgd.width=image.width;                    imgd.height=image.height;                {           &N      Bsp {  }      </script>     Call method:   Code as follows: <a href= "ADMIN/<? echo $rscase [' Path ']?> ' target= ' _blank ' ><img src="ADMIN/<? echo $rscase [' Path ']?> ' alt=] Click to enlarge the picture "width=" 180 "height=" 180 "onload=" Javascript:drawimage (this,180,); ' Hspace= ' 3 "Vspace=" 3 "border=" 0 "/></a>
