Hello, I used your script to make drag and drop work in codeception using webdriver. For anyone who was having the same problem, this is what I did:

Created a file dnd.js Added in the file the entire jquery library.(my app is in angular2 so it doesn't have jQuery). At the end of the app added This simulatedraganddrop js. And at the end end added jQuery('#style-0').simulateDragDrop({ dropTarget: '#dd-top'});

And in codeception:
$this->executeInSelenium(function(\Facebook\WebDriver\Remote\RemoteWebDriver $webdriver) { $script = file_get_contents('/Users/neciudan/Desktop/apps/codeception/tests/_support/Page/dnd.js'); $webdriver->executeScript($script); }); $this->wait(10);

Hope this helps other people who couldn't figure this out in Codeception.

hello, How to use it in Python.

Can some one please provide some code in Java for Drag and Drop operation using js helper.

Hi All,
I am also facing the same issue. Unable to perform drag and drop operation using protractor on HTML 5 application.

I am using typescript as a language. Please suggest how to use above solution in my case i.e. in typescript. Anyone used above solution if yes then please let me know is that working or not.

Thanks in advance.

If someone has an example how to use it with python, please share

I tested a simple sample with Python,it works well.Thanks you very much for your share.
I also referred this : http://elementalselenium.com/tips/39-drag-and-drop

# coding = utf-8
from selenium import webdriver
import os
from time import sleep

driver = webdriver.Chrome()
driver.implicitly_wait(10)
driver.get('http://the-internet.herokuapp.com/drag_and_drop')

with open(os.path.abspath('drag_and_drop_helper.js'), 'r') as js_file:
    line = js_file.readline()
    script = ''
    while line:
        script += line 
        line = js_file.readline()

driver.execute_script(script + "$('#column-a').simulateDragDrop({ dropTarget: '#column-b'});")
sleep(2)
driver.quit()

I am trying to drag and drop using this JS file in JAVA for IE11 with below code but it is not working.

	// Drag and drop the hidden element
	WebElement targetElement = driver.findElement(By.xpath("//input[@id='User']"));
	WebElement sourceElement = driver.findElement(By.xpath("//input[@id='UserMenu']"));

    //Drag 1st control to layout
    String js_filepath = System.getProperty("user.dir") + "/lib/drag_and_drop_helper.js";
    String java_script="";
    String text;

    BufferedReader input = new BufferedReader(new FileReader(js_filepath));
    StringBuffer buffer = new StringBuffer();

    while ((text = input.readLine()) != null)
        buffer.append(text + " ");
        java_script = buffer.toString();

    input.close();

    java_script = java_script+"$('#"+sourceElement+"').simulate( '#" +targetElement+ "');" ;
    ((JavascriptExecutor)driver).executeScript(java_script);

Can anyone tell me what I am doing wrong here?

Thanks a bunch for the information.

I just want to know how to implement for xpath selectors for source and target?

Thank you!

Did you fine any solution for this?

I found the following solution worked without jquery for http://the-internet.herokuapp.com/drag_and_drop https://gist.github.com/reinaldorossetti/074642e9f954b7119c557748836fcd42

Thank you a lot!

I worked as follows in java:

  String filePath = "C://drag_and_drop_helper.js";
  StringBuffer buffer = new StringBuffer();

  String line;
  BufferedReader br = new BufferedReader(new FileReader(filePath));
  while((line = br.readLine())!=null)
      buffer.append(line);

  String javaScript = buffer.toString();
  javaScript = javaScript + "$('#column-a').simulateDragDrop({ dropTarget: '#column-b'});";
  ((JavascriptExecutor)driver).executeScript(javaScript);

Remember that JQuery uses CSS-like syntax. Xpath won't work in this case. If you must use Xpath, you will have to convert the Xpath string to CSS before you append it into this JQuery string:

Pattern pattern = Pattern.compile("'(.*?)'");

  Matcher matcherSource = pattern.matcher("//div[@id='column-a']");

  Matcher matcherTarget = pattern.matcher("//div[@id='column-b']");
  String cssSource = "#" + matcherSource.group(1);

  String cssTarget = "#" + matcherTarget.group(1);
  javaScript = javaScript + "$('" + cssSource + "').simulateDragDrop({ dropTarget: '" + cssTarget + "'});";

@Poncheqa I used your code, but it doesn't work in my case. Nothing changed after execute js script. Can you help me?

My code:

    String filePath = "path/drag_and_drop_helper.js";
    StringBuffer buffer = new StringBuffer();
    String line;
    BufferedReader br = new BufferedReader(new FileReader(filePath));
    while((line = br.readLine())!=null)
        buffer.append(line);

    String javaScript = buffer.toString();
    javaScript = javaScript + "$('#id1 > div > ul').simulateDragDrop({ dropTarget: '#id2 > div > div > div.classDiv'});";
    ((JavascriptExecutor)driver).executeScript(javaScript);

Does this work with sortable.js?

Please any one can help me through this code..I want to perform drag and drop of multiple images..The area i want to drop is a canvas area. i am able t0 drag and drop to that area but i cant drop into specified location or offset values..images are overlapping on each other in one location only..Below is the code snippet..i hav used both javascript executor and action class..

    WebElement source =oBrowser.findElement(By.xpath("//*[@id='tabImg']/ul/li[1]/img"));
    Thread.sleep(5000);
    WebElement target = oBrowser.findElement(By.xpath("//div[@id='canvas']/div/canvas"));

                    .clickAndHold(source)
                    .moveToElement(target)
                    .moveToElement(target,326, 277)
                    .release(source)
                    .build();
    drawOnCanvas.perform();
    actionBuilder.dragAndDrop(source, target).build().perform();

Did you find a solution for this? I'm facing the same issue.

Hi, for all of you who search how to drag and drop element found by XPath: https://sudonull.com/post/3102-How-we-tested-drag-drop-in-HTML5 . I did it in C#, Selenium Web Driver and worked perfect. Note that only the first element is searched by Xpath and the second by css.

Hi All,

I have tried to use this but keep getting this error. Can anyone help what wrong I am doing?

testUtility.dragAndDropElementForHTML5(".e-card-header-title.e-tooltip-text","tr > td:nth-of-type(2)");

Source element CSS: .e-card-header-title.e-tooltip-text
Destination element CSS: tr > td:nth-of-type(2)

public void dragAndDropElementForHTML5(String source, String target)
			throws Exception {
		String js_filepath = System.getProperty("user.dir") + "/src/test/resources/drag_and_drop_helper.js";
		String java_script = "";
		String text;

		BufferedReader input = new BufferedReader(new FileReader(js_filepath));
		StringBuffer buffer = new StringBuffer();

		while ((text = input.readLine()) != null)
			buffer.append(text + " ");
		java_script = buffer.toString();

		input.close();
java_script = java_script + "$('#" + source + "').simulate( '#" + target + "');";
		((JavascriptExecutor) getDriver()).executeScript(java_script);
}

@Rameshwar-Juptimath - You're using an incorrect css selector in either your source or target. You'll need to change the code to :

Old :

java_script = java_script + "$('#" + source + "').simulate( '#" + target + "');";

New :

java_script = java_script + "$('" + source + "').simulate( '" + target + "');";

@rookieInTraining - I tried with the above code but now I'm getting below exception
