Please help me solve this code. I've been fixing this for a month. Thank you for helping!
function copyText(text) {
text.select();
try {
document.execCommand('copy');
} catch (err) {
console.log('Unable to copy' + err);
}
}
copyText('JS is love');
The .select() function call doesn't belong to strings but instead HTMLInputElement such as TextArea
document.execCommand('copy') can only run as a result of an user action. In other words, it must belong inside an EventListener such as 'click'

I'm trying to reload values when switching tab without reloading the page. I'm getting the value from a method.
mounted() {
this.getOriginalSpace();
},
methods: {
getOriginalSpace() {
retrieveQuotaSummary(this.value.organisation, this.value.dataCenter)
.then((result) => {
this.quotaSummary = result;
});
}
}
after that, I read the needed value out of quotaSummary like this (computed):
previouslyYarnCPU() {
return this.quotaSummary.currentAcceptedYarnRequest
? this.quotaSummary.currentAcceptedYarnRequest.cpu
: 0;
},
Then, when I switch tab, and call an other function in computed mode, I still have the same value which was loaded above. But when I refresh the page, then I get the correct (new value).
Can someone please help me, how I can get the latest values without refreshing the whole page?
It is difficult as I would need to see the rest of your code but in order to get values when they change you need to use a computed function. You can read more here
i am trying to put logic when user close the browser/tab then i need to clear the local session. so i have used beforeunload event. The problem is that it's getting called on both browser close as well as on page refresh. and i don't have to clear session on refresh it should be on close.
i tried to check only by using clientY and pageY but it's not working for me.
also i tried with the below code to identify browser is going to refresh or not and set the flag value and use it in beforeunload event. but it's getting called after beforeunload event
this.subscription = this.router.events.subscribe((event) => {
if (event instanceof NavigationStart) {
this.browserRefresh = !this.router.navigated;
if(this.browserRefresh)
{
console.log("browserRefresh");
}
else
{
console.log(" else browserRefresh");
}
}
});
#HostListener('window:beforeunload', ['$event'])
beforeunload($event) {
console.log("clear session");
}
Please suggest if i am using wrong event for the task or suggest me the correct way to this. i checked few links suggested but nothing is helping.
Thanks
You can try like this Hope so it can work
#HostListener('window:unload', ['$event'])
beforeunload($event) {
console.log("clear session");
}
I'm having a heck of a time trying to write a test where I check that text on a button matches a certain string. I tried ".valueContains", ".attributeContains" and got blank or null, and I've tried getText(), but that only seems to return an object.
I feel like it's something obvious I'm missing, so any help would be appreciated!
Based on what you have written so far in your question, I am wondering if there is there a reason you cannot use .containsText?
.waitForElementVisible('.yourclass', this.timeout)
.assert.containsText('.yourclass', 'Text of Button you expect to match')
http://nightwatchjs.org/api#assert-containsText
Without actually looking at the code its little difficult to predict whats going on. However all of the methods in selenium return a promise, so you need to wait for it to resolve.
function async getTextOfButton() {
const element = await driver.findElement(By.className('item-class'));
const text = await element.getText();
}
If you are not using async/await you could do
driver.findElement(By.className('item-class')).then(function(element) {
element.getText().then(function(text) {
console.log(text);
});
});
I have a requirement to disable the escape key when the dialog is open.currently when i click the escape button the dialog closes and the transaction is submitting.I tried the following code snippet but its not working chrome.
dojo.connect(dialog, "onKeyPress", function(e){
var key = e.keyCode || e.charCode;
var k = dojo.keys;
if (key == k.ESCAPE) {
event.preventDefault();
d.stopEvent(event);
}
});
Could you please help on this..i have searched a lot and havent found a suitable solution for my problem.
Thanks inadvance..
Dojo uses the _onKey event for accessibility. You can override it by using:
dialog._onKey = function() { }
I wrote an example JSFiddle, hitting the Escape key should not work anymore.
In the event you want to override the escape key in all dialogs (rather than a particular instance), you can use dojo/aspect:
require(['dojo/aspect', 'dijit/Dialog'], function (Aspect, Dialog) {
Aspect.around(Dialog.prototype, '_onKey', function (original) {
return function () { }; // no-op
});
});
You can create an extension for the Dialog widget like this in a new file:
define(["dojo/_base/declare", "dijit/Dialog"],
function(declare, Dialog){
return declare(Dialog, {
//Prevents the 'ESC' Button of Closing the dialog
_onKey: function() { }
});
});
save the file into dojo Directory (say: dojo/my/my_dialog.js),
and instead of calling: 'dijit/Dialog', just call: 'my/my_dialog'.
this will save you the hard work of editing each Dialog call,
And the same thing to the "dojox/widget/DialogSimple" Widget.
dojo newbie - giving it a shot.
After submitting a form, If an error is returned from the server I would like to show that message on the dijit.form.ValidationTextBox
var user_email = dijit.byId("login_user_email");
user_email.set("invalidMessage", data["result"]["user_email"]);
//need to force show the tooltip but how???
Any help much appreciated.
See it in action at jsFiddle.
Just show tooltip:
var textBox = bijit.byId("validationTextBox");
dijit.showTooltip(
textBox.get("invalidMessage"),
textBox.domNode,
textBox.get("tooltipPosition"),
!textBox.isLeftToRight()
);
Temporarily switch textBox validator, force validation, restore the original validator:
var originalValidator = textBox.validator;
textBox.validator = function() {return false;}
textBox.validate();
textBox.validator = originalValidator;
Or do both at once.
I think you can show the tooltip via myVTB.displayMessage('this is coming from back end validation'); method
you need to do the validation in the validator-method. like here http://docs.dojocampus.org/dijit/form/ValidationTextBox-tricks
you also need to focus the widget to show up the message! dijit.byId("whatever").focus()
#arber solution is the best when using the new dojo. Just remember to set the focus to the TextBox before calling the "displayMessage" method.
I am using dojo 1.10 which works create as follows:
function showCustomMessage(textBox, message){
textBox.focus();
textBox.set("state", "Error");
textBox.displayMessage(message);
}
Dojo reference guid for ValidationTextBox: https://dojotoolkit.org/reference-guide/1.10/dijit/form/ValidationTextBox.html
I know this question is ancient, but hopefully this'll help someone. Yes, you should use validators, but if you have a reason not to, this will display the message and invalidate the field:
function(textbox, state /*"Error", "Incomplete", ""*/, message) {
textbox.focus();
textbox.set("state", state);
textbox.set("message", message);
}
You can call directly the "private" function:
textBox._set('state', 'Error');
You get the same result as #phusick suggested but with less code and arguably in a more direct and clean way.
Notes:
_set is available to ValidationTextBox as declared on its base class dijit/_WidgetBase.
Live demo:
http://jsfiddle.net/gibbok/kas7aopq/
dojo.require("dijit.form.Button");
dojo.require("dijit.form.ValidationTextBox");
dojo.require("dijit.Tooltip");
dojo.ready(function() {
var textBox = dijit.byId("validationTextBox");
dojo.connect(dijit.byId("tooltipBtn"), "onClick", function() {
dijit.showTooltip(
textBox.get('invalidMessage'),
textBox.domNode,
textBox.get('tooltipPosition'), !textBox.isLeftToRight()
);
});
dojo.connect(dijit.byId("validatorBtn"), "onClick", function() {
// call the internal function which set the widget as in error state
textBox._set('state', 'Error');
/*
code not necessary
var originalValidator = textBox.validator;
textBox.validator = function() {return false;}
textBox.validate();
textBox.validator = originalValidator;
*/
});
});
