我正在尝试使用通过 URL 传递的变量预先填充我的表单值。我尝试了许多不同的解决方案,有时我没有收到错误,变量只是没有显示。任何帮助表示赞赏,谢谢!
URL 示例:website.com/?firstname=john
代码:
<html>
<script type="text/javascript">
function writeform(){
selobj = document.getElementById('selform');
newobj = document.getElementById('newform');
p = document.getElementById('menu').selectedIndex + 1;
a = document.getElementById('menu2').selectedIndex + 1;
if((p < 14 && (a == 1 || a == 2 || a == 3 ||a == 4)) { // write the 1st form
txt = 'Person 1: '+'<input type="text"/><br/>';
txt += 'Person 2: '+'<input type="text"/>';
} else {
document.getElementById('div1').style.display='block';
}
// if(p==2 && a==1){ // write the 2nd form
// txt ='Name: '+'<input type="text"/><br/>';
// txt+='Addr: '+'<input type="text"/>';}
newobj.innerHTML=txt;selobj.style.display='block';
}
</script>
