这个function改造下：function ToSa(va){var ctrl = ('input:focus');cc=$(ctrl).val();if(cc==''){$(ctrl).val(va);}else{$(ctrl).val(cc+va);}}

有只小跳蛙

修改ToSa函数var index=1;function ToSa(va){var cc=document.getElementById("sz_a_"+index++)if(cc.value==''){cc.value=va;}}，还有你的那个x按钮时什么功能，不说不好改

HUX布斯

最好把input的onClick事件改成onfocus
