javascript函数完成后提交表单[PHP]
[英]Submit form after an javascript function is completed [PHP]
问题描述
Merry Christmas everyone. 
大家圣诞快乐。 I'm building a small landing page and i have a form in it. 我正在构建一个小的目标网页，并且其中有一个表单。 I have monetized this form with CPA offers, what i would like to happen is to get the user input AFTER the content locking widget has closed. 我已经使用CPA产品通过此表格获利，我希望发生的是在内容锁定小部件关闭后获取用户输入。 I tried many ways but im having errors, and the form submits itself once you click the button and the user doesn't haves to complete the offers. 我尝试了很多方法，但是我遇到了错误，单击按钮后表单便会自动提交，而用户不必完成报价。 The javascript function i have to call is call_locker(); 我必须调用的javascript函数是call_locker();
How can i submit my form after the call_locker(); 我该如何在call_locker();之后提交表格call_locker(); function is completed? 功能完成了吗？

Set id attribute as "myForm" for your form and use the following at the end of your javascript function. 将表单的id属性设置为“ myForm”，并在javascript函数末尾使用以下内容。
document.getElementById("myForm").submit();
EDIT: And call the function with the button click instead of using submit button. 编辑：并单击按钮而不是使用提交按钮来调用该函数。

You need to prevent the submit button from submitting the form, hence use: "event.preventDefault();" 您需要阻止“提交”按钮提交表单，因此请使用：“ event.preventDefault（）;” or "return false;" 或“返回假”； event.preventDefault() vs. return false event.preventDefault（）与返回false
Then at the end of your scripts you can submit the form by using: document.getElementsByTagname("form")[0].submit(); 然后，可以在脚本末尾使用以下方式提交表单：document.getElementsByTagname（“ form”）[0] .submit（）;
