JS 问题，试图在单词之间添加空格

Question

I am having a little issue with my JS code.

I have written the below but i cant seem to add spaces between the words?

var textareas = document.getElementsByTagName("textarea");
var values = textareas [0].value ;
var vals = values.s
var result =  ""

for (i = 0 ; i < vals. length ; i ++ ) {
   if (vals [i] == '') {

  }
}

textareas[1].value = result;

as you can see that there are spaces between the numbers which would need to match the word spacings?

the text area is a HTML element, and i want to add spaces between the words so it pastes

this them their

instead of

thisthemtheir in the text area

Thanks

One thing is that if you have spaces in the source text (ie between the numbers), you need a space in the comparison. So, it should be:

if (vals [i] == ' ')

and not

if (vals [i] == '')

Also, change the line:

result += [ ]

to read

result += ' '

Here it is working with spaces:

 var values = "42,54,53,43, ,42,54,57,49"; var vals = values.split(","); var result = "" for (i = 0; i < vals. length; i ++ ) { if (vals [i] == ' ') { result += ' ' } else { result += String.fromCharCode (31 + 127 - parseInt (vals [i])); } } console.log(result);
