所以我正在为一个客户端开发一个项目，他们正在使用Bootstrap 3的表单验证小部件。还有一个提交按钮，我正试图在上面放置一个自定义的".click(("事件，但无论如何都没有调用它。
在inspect元素中，我可以看到bootstrap.min.js中有很多点击事件处理程序。我认为这是罪魁祸首。过去有人有这个问题的经验吗？
代码：
var fieldsFilled = false;
//Iterate through all the input fields/textarea of the feedback form
$('#fbForm').find('input, textarea').each(function () {
//Each time a key is pressed while the input has focus
$(this).keyup(function () {
//Check if fields are empty
fieldsFilled = checkFormFieldsEmpty('#fbForm') && $('#terms').is(":checked");
//If fields are filled and terms is checked then enable Submit
if(fieldsFilled) {
$("#btnSubmit").css("pointer-events","auto");
} else {
$("#btnSubmit").css("pointer-events","none");
}
});
});
$('#terms').change(function () {
fieldsFilled = checkFormFieldsEmpty('#fbForm') && $('#terms').is(":checked");
if(fieldsFilled) {
$("#btnSubmit").css("pointer-events","auto");
} else {
$("#btnSubmit").css("pointer-events","none");
}
});
//Checks if the form id has blank text fields
function checkFormFieldsEmpty(id) {
var filled = true;
$(id).find('input, textarea').each(function () {
//Check whether the input/textarea is blank
if(!$(this).val()) {
//If the input/textarea is empty return false
filled = false;
}
});
return filled;
}
$(document).on('click', '#btnSubmit', function (event) {
alert('this');
if($('#btnSubmit').hasClass('disabled')) {
alert('empty');
} else {
grecaptcha.execute();
grecaptcha.render();
}
});

这是表单标记中的type="submit"按钮。它的正常行为是提交表单，结果是重新加载页面(或加载在打开表单标记的action属性中找到的URL(。这是瞬间的。它不会"等待"实际页面上其他任何内容的执行。
如果你想在提交之前执行任务，你必须防止这种正常行为：
$(document).on('click', '#btnSubmit', function (event) {
event.preventDefault();
// ... Your additionnal validations
// When ready to submit:
$(this).closest("form").submit();
});
顺便说一下，这个条件if($('#btnSubmit').hasClass('disabled'))永远不会成立。。。因为单击事件不会在禁用的元素上激发。
