我写了下面的内容,以便在CANVAS中绘制任何内容,但它无效。
Socket toA=new Socket("127.0.0.1",socketPortA); //connect to A
toA.getOutputStream().write(1);
在调试模式下,这可以工作但通常不会。有时候它有效,有时它不会。
因此DOM中有一个canvas元素,下面是HTML代码
Actions builder = new Actions(browser);
Action drawAction = builder.moveToElement(webElement,135,15) //start points x axis and y axis.
.click()
.moveByOffset(200, 60) // 2nd points (x1,y1)
.click()
.moveByOffset(100, 70) // 3rd points (x2,y2)
.doubleClick()
.build();
drawAction.perform();
运行代码时,有时绘制画布代码有效,有时则无效。
使用下面的代码等待canvas元素可见。
<fieldset class="signature kyc-signature odd field_with_errors has-
drawn" data-field="Registration::Field::Signature" data-field-
name="registration[signatureImageData]" data-name="
[["legalPerson","firstName"],["legalPerson","lastName"]]">

public void drawCanvas() {
Actions builder = new Actions(browser);
JavascriptExecutor executor = (JavascriptExecutor) browser;
executor.executeScript("arguments[0].scrollIntoView();", webElement); //Scroll the page and move where the element is located
Action drawAction = builder.moveToElement(webElement, 135, 15) //start points x axis and y axis.
.click()
.moveByOffset(200, 80) // 2nd points (x1,y1)
.click()
.moveByOffset(100, 100)// 3rd points (x2,y2)
.doubleClick()
.build();
drawAction.perform();
