| | Привет, всем! Я плохо знаю javascript, помогите мне. Мне нужно чтоб при выборе ождной их 2-х радио кнопок, а именно первая "Кирилица", вторая "латиница", менялась цифра 70 на 140 вот тут -
..... displaylimit("document.limitForm.limit", "", 70);
</script>
|
Сам код:
<textarea name="limit" cols="5" class="sms" align="top"></textarea>
<br>
<script type="text/javascript">
var ns6=document.getElementById&&!document.all
function restrictinput(maxlength, e, placeholder)
{
if (window.event && event.srcElement.value.length >= maxlength)
return false;
else if (e.target && e.target == eval(placeholder) && e.target.value.length >= maxlength)
{
var pressedkey = /[a-zA-Z0-9\.\,\/]/;
if (pressedkey.test(String.fromCharCode(e.which)))
e.stopPropagation();
}
}
function countlimit(maxlength, e, placeholder)
{
var theform = eval(placeholder);
var lengthleft = maxlength-theform.value.length;
var placeholderobj = document.all ? document.all[placeholder] : document.getElementById(placeholder);
if (window.event || e.target&&e.target == eval(placeholder))
{
if (lengthleft < 0)
theform.value = theform.value.substring(0, maxlength);
placeholderobj.innerHTML = lengthleft
}
}
function displaylimit(thename, theid, thelimit)
{
var theform = theid != "" ? document.getElementById(theid) : thename;
var limit_text = 'Осталось <span id="' + theform.toString() + '">' + thelimit + '</span> символов';
if (document.all || ns6)
document.write(limit_text)
if (document.all)
{
eval(theform).onkeypress = function(){ return restrictinput(thelimit, event, theform)}
eval(theform).onkeyup = function(){ countlimit(thelimit, event, theform)}
}
else if (ns6)
{
document.body.addEventListener('keypress', function(event) { restrictinput(thelimit, event, theform) }, true);
document.body.addEventListener('keyup', function(event) { countlimit(thelimit, event, theform) }, true);
}
}
displaylimit("document.limitForm.limit", "", 70);
</script>
