我当前正在尝试弹出一个不使用jQuery的按钮的对话框?我知道JS只能有两个按钮对话框(确认(。但是想知道是否有工作?如果是,怎么样?预先感谢。
您需要使用模态对话框。这可以使用香草JS创建。我从W3Schools(https://www.w3schools.com/howto/howto_css_modals.asp(借了一些代码 - 几乎全部 - 就我而言。他们的示例提供了模态窗口的代码。我已经将其修改为有3个按钮并添加了一个" onclick"事件处理程序,该操作程序触发了一个警报框,显示了该值。
// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
} <
/script>
<
script >
// Add an 'onclick' handler to alert the value of the button clicked.
document.querySelectorAll('.option_button').forEach(function(optionButton) {
optionButton.onclick = function() {
window.alert(optionButton.value)
}
});
