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"));
    Thread.sleep(5000);

    Actions actionBuilder=new Actions(oBrowser);          
    Action drawOnCanvas=actionBuilder
                    .moveToElement(source,223, 184)
                    .clickAndHold(source)
                    .moveToElement(target)
                    .moveToElement(target,326, 277)
                    .release(source)
                    .build();
    drawOnCanvas.perform();
    actionBuilder.dragAndDrop(source, target).build().perform();
    Thread.sleep(5000);

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);
}

Error:

@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

What if I don't have IDs for the elements? Is there any other way around?

@cnparmar Did you find a workaround for this?

hello, any solution for ReactJs? Thanks
