Question

Reg. exp. in javascript to get last <a> tag in substring

Answer 1

+1 A:

get jQuery or Prototype.js in prototype you'd write something like

$$("tr td .Text a").map(function(el) { return el.innerText });

which would return what you want.

I do not have the option on using jQuery or Prototype.

+1 A:

I think that you should rather read the information from the elements than to get the entire HTML code of the page.

Using jQuery you can easily get the information:

var texts = $('span.Text a').map(function(){ return this.html(); }).get();

Using plain Javascript it is a bit harder to traverse elements that doesn't have identities. If you can add id="Text" to your span, it gets easier:

var links = document.getElementById('Text').getElementsByTagName('a');
var texts = [];
for (var i = 0; i <  links.length; i++) texts.push(links[i].innerHTML);

Thanks for the answer - but ,again, i dont have the option of using jQuery, so i need to do it in plain js.

I dont have the option to give it an ID.

sunebrodersen 2010-09-16 07:00:01

But im thinking - if i could search for a span tag with class=Text and then within this tag get all a tags. But im not sure how to get this. I can get the span tag with class=Text fine and store the innerHTML in a var, but how to get from there im not sureMy code: for(var i = 0, n = spanArray.length; i < n; ++i) { if(spanArray[i].getAttribute("class") == 'Text') { //Do some stuff here} }

sunebrodersen 2010-09-16 07:02:52

maybe i could set the ID here and then traverse using your code?

sunebrodersen 2010-09-16 07:06:29

that seemed to work

sunebrodersen 2010-09-16 07:09:15

@sunebrodersen: Once you have the span element you don't need the id. Just call the getElementsByTagName on it to get the links inside it: `var links = spanArray[i].getElementsByTagName('a');`.

Hi,

Thanks for all the answers! Escpecially Seth and Guffa got me back on the right track :)

Here is my solution:

    for(var i = 0, n = spanArray.length; i < n; ++i) {
        if(spanArray[i].getAttribute("class") == 'Text') {
            spanArray[i].id = 'mltracking_breadcrumbs';
            var links = document.getElementById('mltracking_breadcrumbs').getElementsByTagName('a');
            var texts = [];
            for (var j = 0; j <  links.length; j++) {
                texts.push(links[j].innerHTML);
            } 
            alert(links.length);
        }
    }

I know its sensitive about more than one spantag with the classname Text, so please let me know if there are a better option. I dont have ID on the span tag, and dont have the option to get it.
