我正在尝试传递来自body.php的值
Can you please give me example of passing value from javascript to PHP through hidden field?
Thanks.
I'm trying to pass the value from body.php
<html>
<head><script type="text/javascript" src="../js/script.js"></script</head>
<body>
<form name="myform" method="post"
önSubmit="return validateRadio()" action="">
<table class="tftable" border="1">
<tr><th><div align="center" class="tftable th">Questions</div></th><th colspan="2"><div align="center">Answer</div></th>
</tr>
<tr>
<td>I like to dance</td>
<td>
<label></label>
<label>
<input name="bm1" type="radio" value="1" />
Yes</label>
</td>
<td>
<label></label>
<label>
<input name="bm1" type="radio" value="2" />
No
</label>
</td></table></form>
<?php
if (isset($_GET['myval']))
{
echo "VALUE PASSED : ".$_GET['myval']."<br>";
}
?>
</body>
</html>
这里是script.js
Here's script.js
function validateRadio()
{
// get all the inputs type
var inputs = myform.elements;
var radios = [];
// find the radio type
for (var i = 0; i < inputs.length; ++i) {
if (inputs[i].type == 'radio') {
radios.push(inputs[i]);
}
}
var countChecked = 0;
for (var j = 0; j < radios.length; j++) {
if (radios[j].checked) {
countChecked++;
}
}
//count number of radio button with value=1
var answeramount = 0;
for (var k = 0; k < radios.length; k++){
if(radios[k].checked && radios[k].value==1){
answeramount++;
}
}
if (countChecked != radios.length / 2){
alert("All questions must be answered.");
return false; // abort submit
} else {
window.location.href = "body.php?myval=" + answeramount;
return true; // proceed to submit
}
}
回音VALUE PASSED：。$ _ GET ['myval']不起作用......
请帮忙.. 。
The echo "VALUE PASSED : ".$_GET['myval'] doesn't work...
Please help...
