Question

如何使用 jQuery 打开 Bootstrap 4 模式对话框？

我可以使用如下按钮打开一个模态框，该按钮将打开一个包含以下 div 的对话框:

<input type="button" 
       name="PurchaseOrderButton" 
       value="Find" 
       class="btn btn-primary" 
       data-toggle="modal"
       data-target="#id-FindModal" 
       id="id-FindBtn" 
       />

<div class="modal" id="id-FindModal">

我需要运行一个 JavaScript 函数来执行一些步骤，然后加载模式。我尝试使用以下语句进行操作，但不起作用:

$('#id-FindModal').modal('show');

Answer 1

您对显示模式的调用没有问题，很可能您的 Bootstrap 库或 jQuery 库未加载。确保它们是..

这是一个确认您的方法的工作示例:

runCommands()


function runCommands() {
  // run commands
  $('#id-findModal').modal()
}
