我有一个输出字符串的CasperJS脚本，如何修剪文本

Question

Here is my script from CasperJS:

var casper = require('casper').create();
var url = 'https://example.wsw/';
casper.start('https://example.wsw/login.html', function() {
    //this.echo(this.getTitle());
    //this.download(url, 'google_company.html');
    this.echo(this.getHTML('img#cpt_img', true));
});

casper.run();

The out put I get from this is:

<img id="cpt_img" src="/user/turing/image.asp?1394574424">

and this is what I am trying to get it the output:

/user/turing/image.asp?1394574424

so I can use this string above later when I need it.

Can anyone show me away to change the string to what I need in the output?

Answer 1

You can try this:

var imgTag = this.getHTML('img#cpt_img', true);
var src = imgTag.match(/src="(.*?)"/)[1];

尝试使用此：

this.echo(this.getElementAttribute('img#cpt_img', 'src'));
