如何忽略元素点击虽然看不到硒

Question

我正在开发selenium，在运行Java代码时，我试图从网页上访问一个文本框，但是selenium。ElementNotVisibleException:元素当前不可见，因此可能不会与命令持续时间或超时错误交互。

文本字段的代码：

<input type="text" name="TotalTaxPercent" id="TotalTaxPercent" value="19.00" class="smallinputField rightAlign" size="7" onblur="javascript:validateDecimal(this, 5)">

访问文本字段的JAVA代码：

public void setItemTaxValue( String value){
  //By writableTag = By.name("TotalTaxPercent");
  By writableTag = By.xpath("//a[contains(@title,'Override total tax percent')]"); 
  this.sleep(3);
  if (this.waitForExistence(writableTag,35))    {
    this.textfieldSetText(writableTag, value);
    clickOnOK ();
    //          
  } else{
    JLog.fail("Unable to find a writable item taxdialog!");
  }         
}

错误树 ：

[2015-07-14 20:19:24 PDT] FAIL: org.openqa.selenium.ElementNotVisibleException: Element is not currently visible and so may not be interacted with

敬请指教，谢谢

Answer 1

只需捕获异常：

try {
  this.textfieldSetText(writableTag, value);
} catch (ElementNotVisibleException e) {
  JLog.fail("Unable to find a writable item taxdialog!");
}

Answer 2

可能使用JavaScript执行整个操作，因为它是一个隐藏字段

String script = "document.getElementById('TotalTaxPercent').setAttribute('value','20.00');";
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript(script);

如果J奎里是一个选项，那么请尝试

String script = "$('#TotalTaxPercent').prop('value', 20.00);";
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript(script);
