I try to figure out where and how I can make a split/add space between numbers and letters. Cause some people type for example "ip1500" and the script cant match the input with an element that is like "ip 1500". My problem ist that Im a js beginner.

I was trying and trying but i cant get it work. I also tried this

I found this spot and I think it can be done here where the everything get splitted by an " " (space):

prepareQuery: function (val) {
    return val.toLowerCase().split(' ');
    }, 

Would be very nice if somebody can help me.

If you want "123abc345def" to "123 abc 345 def". The replace function may help. The code is like this.

var str = "123abc345def";
str = str.replace(/(\d+)/g, function (_, num){
    console.log(num);
    return ' ' + num + ' ';
});
str = str.trim();

The code you linked didn't work mainly because it's using a different programming language to javascript. In theory, it should work, but javascript does not support regular expression lookbehinds (at this present time)..

Instead, I have re-wrote that fragment of code:

prepareQuery: function (val) {
function isNotLetter(a){
return (/[0-9-_ ]/.test(a));
}

var val=val.toLowerCase().split("");
var tempArray=val.join("").split("");
var currentIndex=1;

for (var i=0;i<val.length-1;i++){
if (isNotLetter(val[i]) !== isNotLetter(val[i+1])){
tempArray.splice(i+currentIndex, 0, " ");
currentIndex++;
}
}
return tempArray.join("");
}

Since you're new to javascript, I'm going to explain what it does.

1. It declares a function in prepareQuery to check whether or not a string contains a letter [this can be moved somewhere else]
2. It then splits val into an array and copies the content of val into tempArray
3. An index is declared (explained later)
4. A loop is made, which goes through every single character in val
5. The if statement detects whether or not the current character (val[i] as set by the loop) is the same as the character next to it (val[i+1]).
6. IF either one are different to the other (ie the current character is a letter while the next isn't) then a space is added to the tempArray at that "index"
7. The index is incremented and used as an offset in #6
8. The loop finishes, joins the "array" into a string and outputs the result.

EDIT: Sorry, but I pletely misinterpreted your question... You failed to mention that you were using "quicksearch" and jQuery. In that case I'm assuming that you have a list of elements that have names and you want to search through them with the plugin... A much easier way to match the user's query (if there is no space) is to strip the space from the search table along with the query itself - though original reverse method will work (just not as efficiently) [aka: expanding the user's query]

In this case, stripping the space from both the search table and user input would be a better method

    prepareQuery: function (val) {
        return val.toLowerCase().replace(/ /ig,'').split(" ");
    },
    testQuery: function (query, txt, _row) {
        txt=txt.toLowerCase().replace(/ /ig,'');
    for (var i = 0; i < query.length; i += 1) {
        if (txt.indexOf(query[i]) === -1) {
            return false;
        }
    }
    return true;

}

Edit 2:

It seems like your real intent is to create a fully functioning search feature on your website, not to just add spaces between letters and numbers. With this, I suggest using Quicksilver. I would love to work out an algorithm to extend quickSearcher but at the current time I cannot (timezones). Instead, I suggest using Quicksilver
