Need help in adding selected items from selectbox to div (dynamic addition)
I need to display the selected sub-categories (multi) in the below div and also in some situations I need to close the div elements that are selected wrongly from the select box, so that I can add and delete elements to the div (by the above selectbox).
Even I made the similar code, but its not working for multi selection.
Briefly, I need the selected categories (multi) with close buttons in the below div.
<script type="text/javascript">
function selectlist() {
checkboxhome = document.getElementById("check");
catogery = document.getElementById("cat");
value = catogery.options[catogery.selectedIndex].value;
checkboxhome.innerHTML = "<br/> <p>" + value + "</p>";
}
</script>
<body>
<form action="#" enctype="multipart/form-data">
<select name="cat" id="cat" onchange="selectlist();" multiple="multiple">
<option>Select subcatogery</option>
<option value="fashion">Fashion</option>
<option value="jewelry">Jewelry</option>
<option value="dresses">dresses</option>
<option value="shirts">Shirts</option>
<option value="diamonds">Diamonds</option>
</s开发者_开发问答elect>
<div id="check">
</div></form>
</body>
</html>
Loop over the options and check if they are selected, something like this:
function selectlist() {
var checkboxhome = document.getElementById("check");
var category = document.getElementById("cat");
checkboxhome.innerHTML = '';
for (var i = 0; i < category.options.length; i++) {
if (category[i].selected) {
checkboxhome.innerHTML += "<p>" + category.options[i].value + "</p>";
}
}
}
Here is a fiddle of what could work for you: http://jsfiddle.net/maniator/W6gnX/
Javascript:
function selectlist() {
checkboxhome = document.getElementById("check");
catogery = document.getElementById("cat");
value = getMultiple(catogery);
checkboxhome.innerHTML = "<br/> <p>" + value + "</p>";
}
function getMultiple(ob)
{
var arSelected = new Array(), length = ob.length, i = 0, indexes = [];
while (ob.selectedIndex != -1 && i < length)
{
if (ob.selectedIndex != 0 && !in_array(ob.selectedIndex, indexes)) {
indexes.push(ob.selectedIndex)
arSelected.push(ob.options[ob.selectedIndex].value);
}
ob.options[ob.selectedIndex].selected = false;
i++;
}
var count = 0;
while(count < indexes.length){
ob.options[indexes[count]].selected = true;
count ++;
}
return arSelected;
}
function in_array(needle, haystack)
{
for(var key in haystack)
{
if(needle === haystack[key])
{
return true;
}
}
return false;
}
