解决方案
您需要找到输入元素提交表单
$(document).ready(function(){
$(。post_comment)。submit (函数(e){
e.preventDefault();
var s = $(this).find(。comment)。data('i');
alert(s );
var value = $(this).find(。comment).val();
alert(value);
});
})
您的标记中还有一个拼写错误, class ='commment' code>应该是
class ='comment'
- 在你的类名中有3 m
演示:小提琴
注意:使用控制台日志记录进行调试,而不是使用 alert()
I have a for loop that shows two forms with input button, how will i get the value of the input button?
<link rel='stylesheet' href='CSS/nook.css' type='text/css' media='screen, projection' />
<script type="text/javascript" src="JS/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function()
{
$(".post_comment").submit(function(e)
{
e.preventDefault();
var s = $(".comment").data('i');
alert(s);
});
})
</script>
<?php
for($i=0;$i<2;$i++){
echo "<form class='post_comment'>";
echo "<div><input type='submit' class='commment' data-i = '$i' value='$i'/></div>";
echo "</form>";
}
?>
解决方案
You need to find the input element which is inside the submitted form
$(document).ready(function () {
$(".post_comment").submit(function (e) {
e.preventDefault();
var s = $(this).find(".comment").data('i');
alert(s);
var value = $(this).find(".comment").val();
alert(value);
});
})
You also have a spelling mistake in your markup, class='commment'
should be class='comment'
- there are 3 m
in your class name
Demo: Fiddle
Note: Use console logging for debugging instead of alert()
