Can you guys tell me what are the differences between onChange and onSubmit while using it in react ???
I have search through all of the google and still haven't find an convincing answer :/

onChange fires any time the user changes an element's value.
onSubmit fires when a form is submitted.

Well, I know this question has been asked before a few times but I'm just a beginner and still couldn't solve it.
I want to set the minimum date of the input date picker to today. In many answers I found the datepicker() method but my webstorm doesn't know this method.
my code:
$("#date").datepicker("option","minDate", new Date(2020,6,5) );
Any tipps for me? Thanks a lot.
Without thinking much about it, it's most likely because you didn't include jQuery UI. datepicker() is a jQuery UI only method.

I am using OpenUI5 and I want to disable an input field. I've already tried the following, but it is not working:
sap.ui.getCore().byId("xxx").setDisabled(true)
The input control does not have a 'disabled' property so the setter setDisabled will not work. However it does have a enabled property so you could use the setEnabled method.
sap.ui.getCore().byId("xxx").setEnabled(false); //Disables the control
If you want to prevent the user from editing the Input value, you should set it's editable property to false using the Input's method setEditable(false).

When I click the outside area of the form, the form will disappear.
I implement this functionality on Chrome.
$(window).on("click", function(e) {
if( !$(event.target).closest('#login_form').length && !$(event.target).closest('#popup_btn').length ) {
$("#login_form").fadeOut("slow");
$("#popup_btn").fadeIn("slow");
$(".nk-header-table").attr("id", "");
}
});
but it doesn't work on Mozilla.
because of the closest() method, I think.
How can I handle it?
Try e.target instead of event.target.

I have created the javascript based demonstration and now I want to hide an image on click in certain condition only.
$("#clear").click(function(){
if ($('#image').is(":visible") && ('#image2').is("hidden")) {
$("#image").hide();
};
});
As you can see my code is not right, so I want to know how to format my code properly. I couldn't find the right way to write multiple conditions in one string. Thanks in advance.
The problem is that you forget to add $ (jQuery) to your second condition and selector hidden is incorrect, should be :hidden:
if ($('#image').is(":visible") && $('#image2').is(":hidden"))
