<P>我在jsp頁面上顯示了一幅地圖，現在需要從地圖上畫一個矩形區域，把該區域內的圖元集合得到，從而進行分析。但沒有思路，不知道怎樣在jsp頁面上把鼠標劃過的參數得到，誰能幫忙指點一下。謝謝了</P>

<P>用Applet或者javascript捕獲鼠標事件</P>

<P>能否提供一個JS實現的例子？？</P>
<P><A name=25989><FONT color=#000066><B>songqian</B></FONT></A>
：</P>
<P>我還是沒整出來，反編譯了自帶的工具條上selection那個按鈕類，發現它的標簽邏輯挺亂的，到底也沒看出參數是怎么傳到后臺的，請高手幫忙啊</P>
