Count characters/sms using jQuery

Question

I count characters using NobleCount and the following code:

$(\'#message\').NobleCount(\'#messageInfo\',{
            max_chars: getMaxChars(),
            o         


        

Answer 1

I think the following script can produce more accurate calculation of SMS parts:

//field: a text box that contains the SMS Text
//cntField: a text box that will contain the remaining count of characters for each part
//smsCntfield: a text box that will contain the count of parts
//lang: 0 for English, 2 for Arabic
//maxLimit: Maximum count of characters to limit the TextBox, (ex: for 5 SMS in Arabic 331, in English 762
function textCounter(field, cntfield, smsCntfield, lang, maxlimit) {

    part1Count = 0;
    part2Count = 0;
    part3Count = 0;
    part4Count = 0;
    part5Count = 0;
    if (lang == 2) {
        // Arabic
        part1Count = 70;
        part2Count = 63;
        part3Count = 66;
        part4Count = 66;
        part5Count = 66;
    } else if (lang == 0) {
        // English
        part1Count = 160;
        part2Count = 145;
        part3Count = 152;
        part4Count = 152;
        part5Count = 152;
    }

    smsCount = 0;
    smsCharCnt = 0;
    smsTotalCount = 0;

    if (field.value.length <= part1Count) {
        smsCount = 1;
        smsCharCnt = part1Count;
        smsTotalCount = part1Count;
    } else if (field.value.length <= (part1Count + part2Count)) { 
        smsCount = 2;
        smsCharCnt = part2Count;
        smsTotalCount = (part1Count+part2Count);
    } else if (field.value.length <= (part1Count+part2Count+part3Count)) {
        smsCount = 3;
        smsCharCnt = part3Count;
        smsTotalCount = (part1Count+part2Count+part3Count);
    } else if (field.value.length <= (part1Count+part2Count+part3Count+part4Count)) { 
        smsCount = 4;
        smsCharCnt = part4Count;
        smsTotalCount = (part1Count+part2Count+part3Count+part4Count);
    } else if (field.value.length <= (part1Count+part2Count+part3Count+part4Count+part5Count)) { 
        smsCount = 5;
        smsCharCnt = part5Count;
        smsTotalCount = (part1Count+part2Count+part3Count+part4Count+part5Count);
    }

    if (field.value.length > maxlimit) {
        // if too long...trim it!
        field.value = field.value.substring(0, maxlimit);
    } else {
        cntfield.value = smsTotalCount - field.value.length;
        smsCntfield.value = smsCount;
    }

}

example use:

                                                                                                

                                                

                                                (
                                                
                                                )
