Bind your event handler in javascript.
在 javascript 中绑定您的事件处理程序。
<input type="button" id="delete" value='Delete' />
document.getElementById('delete').onclick = function () {
if (confirm('Are you sure?')) {
parent.location='<?php echo "delete.php?id=" . $people['id'] ?>';
}
};

It's possible :)
这是可能的 ：）
On the tag, use the attribute onsubmit like this :
在标签上，像这样使用 onsubmit 属性：
<form onsubmit="return confirm('Are you sure?');">
or using a method
或使用方法
<form onsubmit="return myMethod">
The same for a button on onclick event. If it return false, it will be not clicked.
onclick 事件上的按钮也是如此。如果返回false，则不会被点击。
Remember, if the method return false, the form will not be submited
请记住，如果该方法返回false，则不会提交表单

First of all add an onclick method in your HTML, like:
首先在 HTML 中添加一个 onclick 方法，例如：
**HTML:**
<a class="btn btn-danger" href="some url" onclick="DeleteItem();"></a>
**JavaScript:**
function DeleteItem()
{
var a = confirm("Are you sure to delete this record?");
if(a) {
return true;
}else{
return false;
}
}

HTML also supports a reset button on the form, if you are not attached to using javaScript. You can have a structure like this:
HTML 还支持表单上的重置按钮，如果您不附加使用 javaScript。你可以有这样的结构：
<form>
...
items in your form
...
<input type="reset">
...
</form>
When the reset button is clicked, all of the form inputs will reset to their default values.
单击重置按钮后，所有表单输入都将重置为其默认值。
