Perform a function per occurrence in a string

Question

In jquery, how can I perform an alert each time a video tag occurs in a string. Could I base something upon the each function? Let's say the string is called "getTheCurrentResults".

$(getTheCurrentResults["video"]).each(function ()
{
alert ("hello");
});

Please give also the "getTheCurrentResults["video"]", what is it? — Mr.Web, Jul 08 '13 at 10:51

if you want to search a substring inside a string then you have to use `Regular expression`. — Spirals Whirls, Jul 08 '13 at 10:55

I don't know what type getTheCurrentResults is , but if it's a HTML , use roasted solution.

If it's not and you have a string and you want to perform an operation on each item :

$.each('27426472247'.match(/7/g),function (i,n){alert(n)})

This , for example , will trigger a function on each '7'.

@AndrewJuniorHoward What if you string contains some text with word video in it (where video doesn't represent a tag) ? – A. Wolff Jul 08 '13 at 11:29

If i understand your question:

$('<div />').html($.trim(getTheCurrentResults)).find('video').each(function ()
{
   alert ("hello");
});

You wrap string inside a jquery object and then use transversal method on the jq object.

@RoyiNamir not true if – A. Wolff Jul 08 '13 at 11:12
I dont understand. he said it is html . the video element is there so whats the problem finding it under the body element ? – Royi Namir Jul 08 '13 at 11:14
even if it's an element string `jQuery(theString)` will do just fine. – Royi Namir Jul 08 '13 at 11:17
@RoyiNamir Ok, you mean not using find maybe. I'm talking about case like this: http://jsfiddle.net/vPJFC/ `var getTheCurrentResults = '';` Or, please illustrate what you mean, i don't get it – A. Wolff Jul 08 '13 at 11:18
find search from childen and benieth. you should add `addBack` which is the new andSelf() http://jsbin.com/isexar/2/edit – Royi Namir Jul 08 '13 at 11:26
@RoyiNamir ya using addBack() is surely better/more readable here, thx for your feedback, i appreciate – A. Wolff Jul 08 '13 at 11:28
Just checked but addBack() cannot works here as it would always returns the self element even it is not a video tag: http://jsfiddle.net/qx6qC/ – A. Wolff Jul 08 '13 at 11:34
yeah. this can not hold all scenarious. thats why it should be a valid html and to search it under the body element. – Royi Namir Jul 08 '13 at 11:36
