问题描述
是否可以在页面中传递变量.下面以我的情况进行评估?
Is it possible to pass variables in a page.evaluate in my case below?
function myFunction(webpage, arg1, arg2){
var page = require('webpage').create();
page.viewportSize = { width: 1920, height: 1080 };
page.open(webpage, function (status){
if (status == 'success') {
page.includeJs("http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js", function(){
page.evaluate(function(){
arg = arg1 + arg2;
console.log(arg);
});
});
}
else { phantom.exit(); }
});
}
我尝试了几种在Internet上找到的方法，但实际上并没有什么方法可以获取其变量.
I tried several methods found on the internet but nothing actually impossible to get to its variables.
在此先感谢您的帮助:)
