如何使用Robot Framework删除字符串中的空格？

My Variable : 54, 22

我的变量:54,22

What I want : 54,22

我想要的是:54,22

I've tried :

我试过了 :

Execute Javascript var a = 54, 22;var x = a.split(' ').join('');return x

执行Javascript var a = 54,22; var x = a.split('')。join(''); return x

and

Execute Javascript var a = 54, 22;var x = a.replace(/\s/g, '');return x

执行Javascript var a = 54,22; var x = a.replace(/ \ s / g,'');返回x

and

log ${str.strip()}

But none of them solved my problem. When I execute these code seperately I got that error:

但他们都没有解决我的问题。当我单独执行这些代码时,我得到了这个错误:

FAIL : WebDriverException: Message: u'unknown error: Runtime.evaluate threw exception: SyntaxError: Unexpected number\n at Object.InjectedScript._evaluateOn (:895:140)\n at Object.InjectedScript._evaluateAndWrap (:828:34)\n at Object.InjectedScript.evaluate (:694:21)\n (Session info: chrome=43.0.2357.124)\n (Driver info: chromedriver=2.12.301325 (962dea43ddd90e7e4224a03fa3c36a421281abb7),platform=Windows NT 6.1 SP1 x86_64)'

How to solve that problem?

2 个解决方案

#1

You're missing commas in your variable, that's why you're getting syntax error:

你在变量中缺少逗号,这就是你得到语法错误的原因:

var a = '54, 22';

#2

Using the String Library

The String library has a Replace String keyword that you can use to remove whitespace, without having to resort to running javascript:

String库有一个Replace String关键字,可用于删除空格,而不必诉诸于运行javascript:

*** Settings ***
| Library | String

*** Test Cases ***
| Example of removing whitespace
| | ${value}= | Replace String | 54, 22 | ${space} | ${empty}
| | Should be equal | ${value} | 54,22

Using the Evaluate keyword

You can run arbitrary python code with the Evaluate keyword. For example:

您可以使用Evaluate关键字运行任意python代码。例如:

*** Test Cases ***
| Example of removing whitespace
| | ${value}= | Evaluate | "54, 22".replace(" ", "")
| | Should be equal | ${value} | 54,22
