Trigger bootstrap modal if a condition statement is not met
提问by mcadamsjustin
Instead of using the default jquery alert popup, I'd like to trigger a Bootstrap Modal. All the tutorials I've read, the modal is triggered by the click(function(){});. I'd like to have if triggered if a condition in my "if statement" is not met. Here is the code I have
我想触发 Bootstrap Modal，而不是使用默认的 jquery 警报弹出窗口。我读过的所有教程，模态都是由click(function(){});. 如果不满足“if 语句”中的条件，我希望触发 if。这是我的代码
var test1 = $('#test').val();
$('#go').click(function() {
if (test1 === "") {
alert("Please enter all values in the fields");
$('#myModal').modal('show');
}

In your case, since the modal has an idof id="#myModal", you need to escape the #within the jQuery selector, $('#\\#myModal').modal('show'):
在您的情况下，由于模式具有idof id="#myModal"，您需要#在 jQuery 选择器中转义$('#\\#myModal').modal('show')：
$('#go').click(function() {
var test1 = $('#test').val();
if (test1 === "") {
$('#\#myModal').modal('show');
}

Remove the '#' from the id and your code should work
从 id 中删除“#”，您的代码应该可以工作
<div class="modal fade" id="myModal">
