How can I convert a numerical value to text in JavaScript?

Question

I would like to convert a numerical value to a text string. I am opening several windows with the window.open() command and I would like these windows not to be on top of each other.

For that I use the argument "left" and "top" in the windows.open command but these parameters need to be text entities.

for (var i = 0; i < final_number; ++i )
{
    left_value=50+(50*i);
    list[i]=window.open(url[i],"","height=500,left=left_value,width=1000");
};

When calculating left_value=50+(50*i), the result is numerical.

The problem is that the window.open() command is expecting a text parameter for left_value.

I thus want to convert left_value from X to "X"

Answer 1

Use string concatenation:

'height=500,width=1000,left=' + left_value

Answer 2

You can construct a string using the plus operator:

for (var i = 0; i < final_number; ++i ) { 
   left_value=50+(50*i); 
   list[i]=window.open(url[i],"", "height=500,left="+left_value+",width=1000"); 
};

Also, I would suggest using a tool like the firefox plugin firebug to help debug your javascript.

Answer 3

For a simple conversion to a string you can use:

strvalue = String(value)

But usually explicit conversions like this are not needed since javascript does automatic type conversions when appropriate.

Answer 4

You can use following string conversion to convert number to string

var intValue=4;
intValue= ''+intValue;

in first statment intValue is of type long and then it will be converted to string. Hope this will help.
