将按钮的 ID 传递到我的模式的文本框

这里是新手。我有一个 insert function 并且工作正常。但是，我想要完成的更多工作是 将我的按钮的 eventID 值传递到我的模式的输入类型文本框 。任何帮助将不胜感激。我提供了以下代码、更多解释和屏幕截图。谢谢你，祝你有美好的一天。

Ajax

<script type="text/javascript">

   $("#insertParticipant").submit(function(event) {
    event.preventDefault();
    $.ajax({

               data: $("#insertParticipant").serialize(),
               type: "post",
               async: false,
               dataType: 'json',
               success: function(response){

//this is my function for opening the modal

 function add_person()

Answer 1

您已经在函数内部传递了 id 即：onclick="add_person('."'".$person->eventID."'".')" 所以在定义函数时只需将该 ID 作为参数并使用 $("#eventID").val(id) 在您的输入中设置该值-盒子。即：

function add_person(id){
$("#eventID").val(id)
//other codes...
}
