如何根据文本框id固定的字符串得到对象？
<INPUT id= "text1 " TYPE= "text " NAME=txt>
<INPUT id= "text2 " TYPE= "text " NAME=txt1>
<INPUT id= "text3 " TYPE= "text " NAME=txt2>
<INPUT id= "text4 " TYPE= "text " NAME=txt3>
<INPUT id= "text5 " TYPE= "text " NAME=txt4>
已知文本框的id前面固定的字符是text，但后面的数字是动态的，并不知道是多少，
请问有办法根据id得到文本框对象的值吗？
