尝试使用JavaScript进行Selenium WebDriver测试的拖放操作时出错 [英] Error when trying to execute drag and drop using javascript for Selenium WebDriver test

问题描述

我尝试使用以下JavaScript调用来模拟Selenium WebDriver测试的拖放，但是出现WebDriver错误.我尝试过这种方式，因为 Actions 类不适用于任何浏览器(Firefox，Chrome).
有人可以告诉我我在做什么错吗?

I have tried to simulate drag and drop for Selenium WebDriver test using the following JavaScript call, but I get a WebDriver error. I tried this way, as with Actions class didn't work on any browser (Firefox, Chrome).
Can someone tell what I am doing wrong?

String filePath = "C://Work//Spica import files//drag_and_drop_helper.js";
String source = "li[draggable='true']";
String target = "#fieldCc";
StringBuffer buffer = new StringBuffer();
String line;
BufferedReader br = null;
try {
  br = new BufferedReader(new FileReader(filePath));
} catch (FileNotFoundException e) {
  e.printStackTrace();
}

try {
  while((line = br.readLine())!=null)
    buffer.append(line);
} catch (IOException e) {
    e.printStackTrace();
}

String javaScript = buffer.toString();
javaScript = javaScript + "$('" + source + "').simulateDragDrop({ dropTarget: '" + target + "'});";
((JavascriptExecutor)getDriver()).executeScript(javaScript);

我得到的错误是:

推荐答案

尝试删除String source = "li[draggable='true']";中的单引号，然后立即尝试.猜想它会起作用.

Try removing the single quotes from String source = "li[draggable='true']"; and try now. guess it will work.

String source = "li[draggable=true]";
