Convert array(object?) to string in javascript

Question

I am trying to convert this array into a string but it gives me the error:

Object [object Array] has no method 'split'

I am converting to a string, so it shouldn't have that problem, I'm not sure why I am getting this error.

My code is:

function preSubmit(){
 var optionTexts = [];
 $("section").each(function(){
 var h2 = $(this).find("h2").text();
 optionTexts.push(h2);
 $("ol li", this).each(function() { optionTexts.push($(this).text()); });
 });
 var optionTextString = optionTexts.toString();
 var splitText = optionTextString.split(",");
 console.log(splitText);
 return splitText;
}

The returned value of typeof splitText gives me [object Array], but I expect string.

• Ry-: If you want a string and you have a string, why are you splitting it back into an array? That's what split does.
• Felix Kling: While you certainly can convert an array to a string (really depends on its values), the question is: Why?
• Lukasz: I need to replace the , with new line, was assuming making a string is easiest way. from there I can just use replace method, I think?
• Felix Kling: It seems like you just want optionTexts.join('\n') or optionTexts.join('<br>').
• Lukasz: @FelixKling oh, yeah that definitely is a lot cleaner. thanks.

Answer 1

And it's true, array doesn't have any split method. You're messing Join and Split methods, one belong to array, the other to string functions.

What you want is:

var splitText = optionTextString.join(",");

• Felix Kling: optionTextString should be optionText.
