How to increase the timeout in CasperJS
提问by user2129794
I am using waitFor(). The code as below:
我正在使用waitFor(). 代码如下：
casper.waitFor(function check() {
return this.evaluate(function() {
return this.evaluate(someFunction, 'variable 1','variable 2','variable 3') === 'yes';
});
}, function then() {
console.log('Done');
});
Am getting this as console output
我把它作为控制台输出
Wait timeout of 5000ms expired, exiting.
How can I increase the timeout?
如何增加超时时间？
EDIT: I have changed the code to
编辑：我已将代码更改为
casper.waitFor(function check() {
return this.evaluate(function() {
return this.evaluate(someFunction, 'variable 1','variable 2','variable 3') === 'yes';
});
}, function then() {
console.log('Done');
},10000);
It's giving me the following error:
它给了我以下错误：
CasperError: Invalid timeout function, exiting.
C:/filename:1720 in _check

As said here,
正如这里所说，
The signature is
签名是
waitFor(Function testFx[, Function then, Function onTimeout, Number timeout])
So, there is an additionnal argument to specify the timeout.
因此，还有一个额外的参数来指定超时。
casper.waitFor(function check() {
//...
});
}, function then() {
//...
}, function timeout() {
//...
}, TIMEOUT_IN_MS);

Use that to increase the timeout of every wait() functions : casper.options.waitTimeout = 20000; (20sec)
使用它来增加每个 wait() 函数的超时时间：casper.options.waitTimeout = 20000; （20 秒）

If you want to increase timeout while leaving the default error message, pass nullas the third argument and number of milliseconds to wait as the fourth argument:
如果要在保留默认错误消息的同时增加超时，请null作为第三个参数和等待的毫秒数作为第四个参数传递：
casper.waitFor(function check() {
return this.evaluate(function() {
return this.evaluate(someFunction, 'variable 1','variable 2','variable 3') === 'yes';
});
}, function then() {
console.log('Done');
}, null, 10000);
