If you want get elements containing a specific class
just use a helper function to scrape the elements you are looking for.
Example:
var casper = require('casper').create();
var ids = ;
function getIdsByClassValue()
// use your selector here eg. '.image'.
var elems = document.querySelectorAll('input[type="submit"]');
return Array.prototype.map.call(elems, function (e)
// change to the attribute you are looking for.
return e.getAttribute('value')
);
casper.start('https://www.google.com/');
casper.then(function ()
ids = this.evaluate(getIdsByClassValue);
);
casper.run(function()
this.echo('n - ' + ids.join('n - ')).exit();
);
You can use getElementsAttribute
to do that.
.getElementsAttribute
Signature: getElementsAttribute(String selector, String attribute)
Retrieves the values of an attribute on each element matching the provided selector:
Here is an example.
var ids = ;
var casper = require('casper').create();
casper.start('https://google.com/', function()
this.wait(1000, function()
ids = this.getElementsAttribute('*', 'id')
.filter(function(id)
return id.length > 0;
)
);
);
casper.then( function()
this.echo('n - ' + ids.join('n - ')).exit();
)
casper.run();
I want to specify by unique class name <div id = 111 class = "image"> <div id = 222 class = "image">

I have made an edit. You would just have to change thequerySelectorAll
and pass in your css class name eg.'.image'
, you also want to change thegetAttribute
to the attribute you are looking for.

return e.getElementById();
does obviously not make any sense, because getElementById
is a function that expect one argument and is only available on the document
.
It seems you want to return the id
property:
var ids = casper.evaluate(function()
return Array.prototype.map.call(document.querySelectorAll("image"), function(e)
return e.id;
);
);
this.echo(ids);
