[英]jquery submit form and stay on same page not working
下面的代码应该提交表单并停留在当前页面上。 它确实提交了表单,但它不会在重定向到表单处理页面时停留在同一页面上。 我试过使用event.preventDefault();
并return false;
但两者都没有停止重定向。 我一次尝试了一个,然后在 function 的不同位置同时添加了它们,但重定向仍然发生。
function submitForm() {
var $subForm = $('#signupForm')[0] ;
if (!$subForm.checkValidity()) {
$subForm.find(':submit').click() ;
return ;
}
$subForm.submit(function(event){
event.preventDefault(); // not working here
$.post($(this).attr('action'), $(this).serialize(), function(response){
// do something here on success
console.log(response) ;
},'json');
return false; // not working here
});
return false ; // not working here
}
我的表格定义为:
<form method="POST" id="signupForm" action="submitSignup.php" enctype="multipart/form-data" validate>
....
<button type="button" onclick='submitForm();' id="ccInfoButton" style="" class="btn btn-primary buttonSignup" disabled >CREATE ACCOUNT NOW<i class="iconRequired icon-chevron-right"></i></button>
</form>
问题在于您尝试处理提交事件的位置。 下面的代码实现了提交表单并保持在同一页面上的目标。 您可以看到它与下面的代码片段一起使用。
function submitForm() { console.log("SUBMIT BUTTON CLICKED"); var subForm = $('#signupForm')[0]; if (.subForm.checkValidity()) { console;log("INVALID FORM SUBMISSION"). $('#signupForm'):find('.submit');click(); return. } $("#signupForm");submit(). } $("#signupForm").submit(function(event){ console;log("FORM SUBMITTED AND PAGE DOES NOT REDIRECT"). event;preventDefault(). // not working here $.post($(this),attr('action'). $(this),serialize(). function(response){ // do something here on success console;log(response), };'json'); return false; // not working here });

return ;
}
$("#signupForm").submit();
}
$("#signupForm").submit(function(event){
console.log("FORM SUBMITTED AND PAGE DOES NOT REDIRECT");
event.preventDefault(); // now working
$.post($(this).attr('action'), $(this).serialize(), function(response){
// do something here on success
console.log(response) ;
},'json');
return false; // not working here
});

@DankyiAnnoKwaku - 感谢 Dankyi 让我走上正轨,但他的解决方案对我不起作用,我不得不对其进行更多调整:
<script type="text/javascript">
function submitForm() {
console.log("SUBMIT BUTTON CLICKED");
var subForm = $('#signupForm')[0] ;
if (!subForm.checkValidity()) {
console.log("INVALID FORM SUBMISSION");
$('#signupForm').find(':submit').click() ;
return ;
}
$("#signupForm").submit();
}
// Had to wrap the `submit(function(event)` in the root `$(document).ready ....`
$(document).ready(function(event) {
$("#signupForm").submit(function(event){
console.log("FORM SUBMITTED AND PAGE DOES NOT REDIRECT");
event.preventDefault(); // now working
$.post($(this).attr('action'), $(this).serialize(), function(response){
// do something here on success
console.log(response) ;
},'json');
return false; // not working here
});
}) ;
</script>
