Omezeni pridani elementu – JavaScript, AJAX, jQuery – Fórum – Programujte.com

Zdravim, v javascriptu jsem uplna lama a potreboval bych poradit s omezenim jednoho scriptu. Je to script na pridavani elementu do stranek. Problem je ten ze to prida nekonecne mnozsti. Chtel bych to omezit treba na 5 maximalne. Jak to udelat?

Diky za rady, napady, odpovedi.

<script>

function addEvent() {

var ni = document.getElementById('myDiv');

var numi = document.getElementById('theValue');

var num = (document.getElementById("theValue").value -1)+ 2;

numi.value = num;

var divIdName = "my"+num+"Div";

var newdiv = document.createElement('div');

newdiv.setAttribute("id",divIdName);

newdiv.innerHTML = "Element Number " + num + " has been added! <a href=\"javascript:;\" onclick=\"removeElement(\'"+divIdName+"\')\">Remove the element ""+divIdName+""</a>";

ni.appendChild(newdiv);

}



function removeElement(divNum) {

var d = document.getElementById('myDiv');

var olddiv = document.getElementById(divNum);

d.removeChild(olddiv);

}

</script>





<input type="hidden" value="0" id="theValue" />

<p><a href="javascript:;" onclick="addEvent();">Přidat další práci</a></p>

<div id="myDiv"> </div>

<script> 

function addEvent() {

if(addEvent.elmCount >= 5) { return; }

addEvent.elmCount++;

 

var ni = document.getElementById('myDiv'); 

...

} 



addEvent.elmCount = 0;
