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).

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.

I have a html page with <html> tag where I want to add dir="rtl" and lang="ar" attributes using jQuery when user click on arabic language in drop-down.
I tried using $(html).attr("dir","rtl")
But it returns undefined. Can somebody help as I'm new to jQuery
There is an error on your code, the "html" tag should be written with quotes as folows:
$('html').attr("dir","rtl")
Ok, the question is closed, answer given, so no use for this answer anymore.

In an app I'm working on, I'd found that updating the DOM by rewriting a new value to innerHTML doesn't give the expected result.
I typed the following command in the DevTools console:
document.querySelector('main-app').shadowRoot.querySelector('.unitslist').innerHTML = '<unit-bar>1</unti-bar><unit-bar>2</unti-bar>'
With the following result:
<unit-bar>1<unit-bar>2</unit-bar></unit-bar>
You have a typo in your strings. You open with <unit-bar>, but close with </unti-bar>. The closing tags are therefore probably ignored by the browser and it guesses where they should be, resulting in the difference you see.
so , you can solve to avoid overwriting: -
1. get the content of the div and that add the current value to update and the existing values
DOMElem.innerHTML = DOMElem.value + (value to be updated)

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"))
