我正在尝试根据用户选择(通过单选按钮)将文本值发布到不同的 python 程序。程序在单一表单操作下运行良好
<form action='/cgi-bin/prog1.py' method='POST'>
...text input1
...text input2
...submit
</form>
但是当使用单选按钮时，文本值不会发布到程序中。
这是我尝试过的代码
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">
function whichsite(form){
var sites = form.elements.site, i = sites.length;
while (--i > -1){
if(sites[i].checked){
return sites[i].value;
}
}
}
</script>
</head>
<body>
<form action="#" onsubmit="window.open(whichsite(this)); return false; method='POST' ">
<b>Program Jump</b>
<p>
Enter PDB ID:<input type="text" name="PDB_ID"><br>
Enter PDB Chain:<input type="text" name="Chain_ID"><br>
<label><input type="radio" name="site" value="/cgi-bin/prog1.py">P-P</label>
<label><input type="radio" name="site" value="/cgi-bin/prog2.py">P-L</label>
<label><input type="radio" name="site" value="/cgi-bin/prog3.py">P-C</label>
<p>
<input type="submit" value="Submit">
</form>
</body>
</html>
帮帮我!
最佳答案
我认为你应该在onsubmit方法而不是window.open方法中更改表单的action属性值，你可以尝试一下像这样:
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">
function whichsite(form){
var sites = form.elements.site, i = sites.length;
while (--i > -1){
if(sites[i].checked){
// here change the action value instead of return the site
form.action = sites[i].value;
}
}
}
</script>
</head>
<body>
<form action="#" onsubmit="whichsite(this); return false;" method="POST">
<b>Program Jump</b>
<p>
Enter PDB ID:<input type="text" name="PDB_ID"><br>
Enter PDB Chain:<input type="text" name="Chain_ID"><br>
<label><input type="radio" name="site" value="/cgi-bin/prog1.py">P-P</label>
<label><input type="radio" name="site" value="/cgi-bin/prog2.py">P-L</label>
<label><input type="radio" name="site" value="/cgi-bin/prog3.py">P-C</label>
<p>
<input type="submit" value="Submit">
</form>
</body>
</html>
或者，你可以尝试改变radio的change事件中action的值，希望对你有帮助~~~
