Add node to jQuery selection
I have a function that applies a wrap to different elements (and does some other stuff that is not relevant for this question). I would like the function to return the globality of the wrap element as jQuery selection. I dont want to have to reselect them.
i have tried something like this:
myfunction(){
return $mythings.each(function(){
$wrap = $("div.wrap");
$(this).wrap($wrap);
//do some other stuff
return $wrap;
});
};
but this was returning $mythings.
So i tried this:
myfunction(){
var $returnOfTheWrap = $();
$mythings.each(function(){
$wrap = $("div.wrap");
$(this).wrap($wrap);
//some different actions
return $returnOfTheWrap.push($wrap);
});
return $returnOfTheWrap;
};
returns $($(wrap));
Any idea how i 开发者_StackOverflow中文版could solve this? I would like to get $(wrap0, wrap1, wrap2) back
I think you are looking for the map function http://api.jquery.com/jQuery.map/
try
<SCRIPT type=text/javascript>
$(function(){
$.each($(".button"),function(i,n)
{
alert(i+ ":" + $(n).html());
});
var wrapped = myfunction($(".button"));
//alert(wrapped.length);
$.each(wrapped,function(i,n)
{
alert(i+ ":" + $(n).html());
});
});
function myfunction(mythings){
return $.map(mythings,function(n,i){
$wrap = $("<div></div>");
$(n).wrap($wrap);
//do some other stuff
return $(n).parent();
});
}
</SCRIPT>
</HEAD>
<BODY>
<button class="button">a</button>
<button class="button">b</button>
<button class="button">c</button>
</BODY>
Maybe you want to try something like this
This returns my listbox options (unedited however) as DOM elements
var existingtitles = $("#existingtitles option").each(function () { return $(this); });
and work this into an array or w/e
