javascript - Trying to use FOR loop inside of the string. (Js, jQuery) - Stack Overflow

I have this code:

$.each(data, function(i,v){
  $('#user-grid').append(
    '<a href="my_urls">' +
      '<div>' + v.points + '</div>' +
      '<div>' + v.other + '</div>' +
    '</a>'
  );
});

Into the user grid div, I append the string with the values taken from data.

v.points and v.other are the numbers.

To this moment, everything works just fine. But what I need is to embed the for loop into the divs. In the places where I have v.points and v.other I want to put two simular FOR loops.

for(var i = 0; i < v.points; i++) {
  //here is the html line that should be passed to the div, where v.points are now
  <div>This is the point</div>
}

And almost the same for the v.other. Only with another line that should be pasted.

So basically how can I do that? I was trying to paste this loops right inside the "append()" but that didn't work out. I was also trying to create a variable inside of the loop and pass it in to the append, but got only one result, instead of all that I have needed.

• 1 Loop inside append won't work (unless it's a functional loop like map). Constructing a variable in a loop then passing it to append should be correct; please show the code you tried to run. Also, very importantly, please make a mock-up of the output you are trying to get (for instance, I don't know if you want points and other to go sequentially or interleaved). – Amadan Commented Jul 27, 2015 at 3:39
• 1 your for loop example is not syntactically valid – knitevision Commented Jul 27, 2015 at 3:41

I'm not sure if this is what are you looking for, this code prints 5 "This is your point" and 3 "This is your other" inside the anchor.

var data = [
    {
        points: 5,
        other: 3
    }
]

function printPoints(vPoints){
    var str = "";
    for(var i=0; i<vPoints; i++) {
        str+="<div>"+"This is your point"+"</div>";
    }
    return str;
}

function printOther(vOther){
    var str = "";
    for(var i=0; i<vOther; i++) {
        str+="<div>"+"This is your other"+"</div>";
    }
    return str;
}

$.each(data, function(i,v){
  $('#user-grid').append(
    '<a href="my_urls">' +
      printPoints(v.points)+
      printOther(v.other)+
    '</a>'
  );
});
