string building and hidden form fields

[empiresolutions]

Hello,

I'm trying to get this script to work, but my deep rooted PHP syntax is messing my JS up.

I have a flash file that calls this JS function. It basically adds a number to a comma separated string. this works fine.

var select = "";
function selectCounty (cid){ select = cid + "," + select; }    
 

The flash also calls this function to remove a value from the string. The removeVal() function works. though, the *select* variable is not reforming into a string. I'm missing how to then put the array into a form that this is part of.

function unSelectCounty (cid){ 
    // split the *select* string into an array
    var select_array = select.split(/,/);
 
    // remove *cid* value from array
    unselect = removeVal(select_array, cid);
 
    // reset *select* var
    select = "";
    for (i=0;i<unselect.length;i++){ if (unselect[i] != ''){ select = unselect[i] + "," + select; } }
}
function removeVal(arr, valToRemove){
    // Normalize to a string like !val!!val!!val!
    var s = '!' + arr.join('!!') + '!';
    // Remove targeted values with delimiters
    s = s.replace(new RegExp('!' + valToRemove + '!', 'g'), '');
    // Remove delimiter added to end in step 1
    s = s.replace(/^!/, '');
    // Remove delimiter added to start in step 1
    s = s.replace(/!$/, '');
    // Convert to array
    return s.split('!!');
}
 

Please help with these two problems-

1) i cant get the *select* string in unSelectCounty() to reform correctly.
2) i am unsure what to write so that the value of *select* is passed in POST form array. it can accept it either as an array or a string.

Thanks.

So r u trying to pass an an array in form fields???
right???

but mind it ... no array can be sent.
all the parameter value is sent as string.
if u want to send multiple value in one string then in the server side u should tokenize the string.
or keep each value in multiple values in multiple fields.
best of luck.

kind regards.

ok i got a little farther, updated this function to -

    function unSelectCounty (cid){ 
        // split the *select* string into an array
        select_array = select.split(/,/);
        // remove *cid* value from array
        unselect = removeVal(select_array, cid);
        // reset *select* var
        select = unselect.join(',');
    }
 
 

I still need to know about how to attach my *select* var to a hidden form field. this can be passed as a string.

join() makes the array a string, so you can simply set the value of the hidden field:

document.getElementById(hiddenid).value=select;
