我在表单中的选择上使用onchange ="this.form.submit()"，它可以按预期工作，但是当您更改选择下拉菜单并让如果单击确定，则提交表单.如果某人有办法做到这一点，请与您分享. -谢谢

I'm using onchange="this.form.submit()" on a select in a form, it works as expected, but I would like an alert to pop up when you change the select drop down and then have the form submit if you click OK. If someone has a way to do that it would be appreciated if you could share it. -thanks

<form action="/index.php/dashboard/pages/page_statistics/change_collection_type/" method="post"> <input type="hidden" value="690" name="cID"> <select onchange="this.form.submit()" name="ctID"> <option value="4">Blog Entry</option> <option value="85" selected="selected">Blog Posting</option> <option value="5">Full</option> </select> </form>

推荐答案

使用确认功能.就像警报一样工作，但是如果用户按确定"，则返回true，如果按取消"，则返回false.

Use the confirm function. Works just like an alert, but returns true if user presses okay, false if they press cancel.

test = confirm("Continue?"); if (test) { this.form.submit() }

因此，对于您来说，您可以将其作为on

so for you, you'd put it on your onchange as

onchange="if(confirm('Continue?')){this.form.submit()}"
