how to get updated hidden field value using Selenium webdriver in java

Question

I am trying to get the hidden field value using below code but getting the default value as 0.69163 .

WebElement hiddenInput = ieDriver.findElement(By.id("form_base_amount_input_hidden"));
String currencyConverted = hiddenInput.getAttribute("value");

old value:

<input name="base_amount" id="form_base_amount_input_hidden" value="0.69163" type="hidden">

new value:

<input name="base_amount" id="form_base_amount_input_hidden" value="383.852" type="hidden">

Answer 1

I think only via JavaScriptExecutor:

JavascriptExecutor je = (JavascriptExecutor) ieDriver;
String script = "document.getElementsById('form_base_amount_input_hidden')[0].setAttribute('value', '383.852');");
je.executeScript(script);

Answer 2

String  text = (String)((JavascriptExecutor) driver).executeScript("return document.getElementsByName('base_amount')[0].value;");  

请执行此语句，希望您能得到结果。
