javascript – how can I cut the code in case the user would say "no" in my confirmation?

I want everything that comes later in my code to be executed only if the user confirms it. In case I say no, I want it to be cut off.

var avanzar = confirm("Esta seguro que desea avanzar?");
    var hachedos = document.querySelector("h2")

if (avanzar==true) {
  hachedos.innerHTML = "Qué alegría que das con tu visita por este maravilloso sitio!!!"

} else {
  hachedos.innerHTML = "Lamentamos que no quieras continuar tu visita por este maravilloso sitio"
};

javascript – how to get a div out of the hidden stream

I have an array with multiple columns and a line that makes data simple. The last column is the action column whose each line contains a drop-down list – edit / stop functions. On the last row, the drop-down menu is cut off, and that's because the table the element has overflow:hidden. This is necessary because the highlight must stop in the last row of the table.

I tried to remove the position: relative of optionSection class but the drop-down list goes to the body. How can I make the drop-down menu come out from where it is – as the picture shows – and do not mess with the overflow:hidden. Is there any alternative to this, have the drop-down menu to go out and stop highlighting on the last line?

You will find below the html and css codes.

..................
1 2 3 4 action
.. .. .. ..
  • Edit
  • Stop

css

table {
    border-top: 1px solid rgba(0, 0, 0, 0.05);
    width: 100%;
    overflow: hidden;}

.optionSection {
    color: #0083C6;
    cursor: pointer;
    position: relative;
    width: 100%;
}

.optionSection .listContainer {
    position: absolute;
    z-index: 1;
    background-color: #FFF;
    width: 100%;
    border: 1px solid #BFBFBF;
    border-radius: 3px;
    top: 0;
    right: 46px;
}

javascript – How to display an error returned by the backend on nodejs in react

I have a problem with the error message that came from the backend. I come back in the backend:

res.status (400) .send ({error: "the user already exists"});

On the front, I would like to display this message instead of the default message displayed:

The query failed with the 400 status code

How can I receive and view this message from the backend?

front code:

try{
    //sucess
}catch(error){

javascript – What is the function of children's courses in angular mode?

Does the child route function in Angular only serve to make the child route component in the parent route component? Because I wanted to do exactly the opposite. I wish that when I go from the parent road to the child route, I want to display on the screen only the child route model. Is there any way to do that?

{path: "my-curriculum", component: MyCurriculumComponent, children: [
{path: "general information", component: CurriculumFormComponent},
{path: "work", component: CurriculumFormComponent},
{path: "education", component: CurriculumFormComponent},
{path: extracurricular activity, component: CurriculumFormComponent}
]}

javascript – Check box does not change its value if unchecked

j & # 39; uses vue-stap and I have the following structure:

checkboxValues: {
    sub_status:  {value: true, name: "Subtest Status"},
    data_name:   {value: true, name: "Data Name"},
    data_status: {value: true, name: "Data Status"}
}

I want to create a checkbox for each of them so that it is ticked accordingly value field.
I have tried:

 {{checkboxValue.name}}

But for whatever reason, it does not change the value of the checkbox if it's unchecked, it's still true. For example, if I go sub_statusthen sub_status.value is always true What could be the problem?

javascript – works in nodejs with callbacks

I followed a tutorial and found an example with promises that looked like this:

function requestName(userName){
	
	const url = `https://api.github.com/users/${userName}`;
	fetch(url)
		.then( function(res){
			return res.json(); 
		})
		.then( function(json){
			console.log(json.name);
		})
		.catch( function(e){
			console.log(`El error es: ${e}`);
		});
		
}

I still learn about the functions but I was trying to do the same thing with Callback but the result does not print anything on the console or maybe I'm doing something wrong, the code is the next:

function requestName(userName){
	const url = `https://api.github.com/users/${userName}`;
	fetch(url, function(err,res){
		if(err){
			console.log(`El error es: ${err}`);
		}else{
			const json = res.json();
			console.log(json);
		}
	})
}
