<input id=1 type=text /> <input id=2 type=text />

请问如何在光标处插入文字,或者在指定input插入文字,附一简单的在唯一input插入文字的JS,求修改function test(str){ //在光标处插入内容 var tc = document.getElementById("text");
var tclen = tc.value.length;
tc.focus();
if(typeof document.selection != "undefined")
{
document.selection.createRange().text = str;
}
else
{
tc.value = tc.value.substr(0,tc.selectionStart)+str+tc.value.substring(tc.selectionStart,tclen);
}
}但是从第一行可以知道他只能指定唯一ID
