Dam tu kod...Nevie mi niekto povedat kde tam mam chybu?ja ju nevidim :(
<form name="form2" class="sandwich_menu">
<input type="checkbox" name="check1" onclick="DisplayCost()" />Cheese<br/>
<input type="checkbox" name="check2" onclick="DisplayCost()" />Turkey<br/>
<input class="form_buttons" type="button" value="Reset" onclick="ClearSettings()"/>
<input type="reset" class="form_buttons" value="Reset_b"/><br/>
<div id="div1"></div>
</form>
A FUNKCIE :
function ClearSettings() {
for (var pocet_poloziek=0;pocet_poloziek<document.form2.elements.lenght;pocet_poloziek++)
{
if (document.form2.elements[pocet_poloziek].type=="checkbox"){document.form2.elements[pocet_poloziek]=false}
}
}
function DisplayCost() {
var suma=0;
for( var pocet_poloziek=0;pocet_poloziek<document.form2.elements.lenght;pocet_poloziek++)
{
if (document.form2.elements[pocet_poloziek].type=="checkbox" && document.form2.elements[pocet_poloziek].checked)
{
suma= suma+1;
}
}
document.getElementById("div1").innerHTML="Celkova suma : " + suma.toPrecision(3);
}
Máš tam preklep v slove lenght, správne má byť length. Poďalšie by si si mal zvyknúť na nejaký prehladnejší zápis kódu, napr. takto:
<script> function ClearSettings () { for (var pocet_poloziek = 0; pocet_poloziek < document.form2.elements.length; pocet_poloziek++) { if (document.form2.elements[pocet_poloziek].type == "checkbox") { document.form2.elements[pocet_poloziek] = false; } } } function DisplayCost () { var suma = 0; for (var pocet_poloziek = 0; pocet_poloziek < document.form2.elements.length; pocet_poloziek++) { if (document.form2.elements[pocet_poloziek].checked) { // suma = suma+1; suma++; } } document.getElementById ("div1").innerHTML = "Celkova suma : " + suma; } </script> <form name = "form2" class = "sandwich_menu"> <input type = "checkbox" name = "check1" onclick = "DisplayCost()" />Cheese<br/> <input type = "checkbox" name = "check2" onclick = "DisplayCost()" />Turkey<br/> <input class = "form_buttons" type = "button" value = "Reset" onclick = "ClearSettings()"/> <input type = "reset" class = "form_buttons" value = "Reset_b"/><br/> <div id = "div1"></div> </form>dakujem
Nieje zač.
