怎样利用javascript，一个checkbox控制多个textbox
一个checkbox控制一个textbox我会，在pageload里，加上
checkbox.attributes[ "onclick "]= "document.getElementById( ' "   +   txt1.clientid   +   " ').disabled=this.checked; ";
再加一个txt2，怎么写？

checkbox.attributes[ "onclick "]= "document.getElementById( ' " + txt1.clientid + " ').disabled=this.checked;document.getElementById( ' " + txt2.clientid + " ').disabled=this.checked; ";

------解决方案--------------------------------------------------------
checkbox.attributes[ "onclick "]= "document.getElementById( ' " + txt1.clientid + " ').disabled=this.checked;document.getElementById( ' " + txt2.clientid + " ').disabled=this.checked; ";

txt1.Attributes[ "disabled "] = "true ";
txt2.Attributes[ "disabled "] = "true ";
