我使用上面的代码来制作颜色选择器，现在我需要将颜色应用于来自文本框的文本，该文本框存储在 table1 的变量中

我需要div_color_click在桌子上应用，即 table1

我使用以下功能来应用颜色，但它不起作用

<script>
function checkbutton()
{
var color=document.getElementById("textcolor").value;
document.getElementById("table1").style.color=document.getElementById("textcolor").innerHTML;
document.getElementsByName("nam").style.color=document.getElementById("textcolor").innerHTML;
}
</script>
