在CasperJS,我處理這個問題,使用了上述方法(一個或多個),並且最終發現當我通過casper.viewport()
方法設置單個視口選項時,它是不必要的(至少對我來說,在CasperJS中)。
我已經在下面發佈了我的版本,所以你可以看到它是如何與許多網址一起工作的。
// Requires node.js and casperjs (npm install casperjs)
var casper = require('casper').create();
var root_dir = 'screenshots/';
var links = [];
var root = 'http://localhost:8001/';
var DEBUG = false;
var opts = {top: 0, left: 0, 'width': 1280, 'height': 1024};
function getHrefs() {
// Taken wholesale from casperjs
// http://docs.casperjs.org/en/latest/quickstart.html
var links = document.querySelectorAll('.days li > a');
return Array.prototype.map.call(links, function(e) {
return e.getAttribute('href');
});
}
function captureLinks(links) {
casper.echo('= SCREEN CAPTURING LINKS ====');
casper.each(links, function(self, link) {
var filename = root_dir + link.replace('/index.html', '') + '.png';
casper.echo('Capturing... ' + filename);
// Relevant code...
this.viewport(opts.width, opts.height);
self.thenOpen(root + link, function() {
// slight delay for external libraries and init loading
this.wait(500, function(){
this.capture(filename, opts);
});
});
});
}
casper.start(root, function() {
links = links.concat(this.evaluate(getHrefs));
this.echo('= GETTING LINKS ====');
if(DEBUG) this.echo(links.join('\n'));
captureLinks(links);
});
casper.run();
