如何在Selenium Webdriver中模拟HTML5拖放? [英] How to simulate HTML5 Drag and Drop in Selenium Webdriver?
问题描述
我想在Selenium WD中自动拖放操作,但根据其他相关帖子 HTML5中的操作不受Selenium的支持有什么办法来模拟Python中的拖放吗?
以下是我尝试的代码:
driver = webdriver。 Firefox()
driver.get(http://html5demos.com/drag)
target = driver.find_element_by_id(one)
source = driver.find_element_by_id(bin )
actionChains = ActionChains(driver)
actionChains.drag_and_drop(target,source).perform()
,它没有起作用。
是的,HTML5拖放目前由Selenium支持:
建议的解决方法之一是模拟HTML5通过JavaScript拖放:
- 下载
drag_and_drop_helper.js
- 通过
execute_script()在
源上调用
simulateDragDrop()
函数来执行脚本c $ c>元素通过目标
元素作为dropTarget
示例代码:
with open(drag_and_drop_helper.js)as f:
js = f.read()
driver.execute_script(js +$('#one')。simulateDragDrop({dropTarget:'#bin'});)
问题是它不会在你的情况下按原样,因为它需要 jQuery
。
现在我们需要弄清楚如何动态加载jQuery 。幸运的是,有解决方案。
完成工作例如在Python中:
从selenium import webdriver
jquery_url =http://code.jquery .com / jquery-1.11.2.min.js
driver = webdriver.Firefox()
driver.get(http://html5demos.com/drag)
driver.set_script_timeout(30)
#load jQuery helper
with open(jquery_load_helper.js)as f:
load_jquery_js = f.read()
#加载拖放帮助
与open(drag_and_drop_helper.js)为f:
drag_and_drop_js = f.read()
#load jQuery
driver.execute_async_script(load_jquery_js,jquery_url)
#执行拖放
driver.execute_script(drag_and_drop_js +$('#one')。simulateDragDrop({dropTarget:'# bin'});)
其中 jquery_load_helper.js
包含:
/ **动态加载jQuery * /
(function(jqueryUrl,callback){
if(typeof jqueryUrl!='string'){
jqueryUrl ='https://ajax.googleapis.com/ajax/libs/jquery/ 1.7.2 / jquery.min.js';
}
if(typeof jQuery =='undefined'){
var script = document.createElement('script');
var head = document.getElementsByTagName('head')[0];
var done = false;
script.onload = script.onreadystatechange =(function(){
if(!done&&&(!this.readyState || this.readyState =='loaded'
|| this.readyState =='complete')){
done = true;
script.onload = script.onreadystatechange = null;
head.removeChild(script);
callback( );
}
});
script.src = jqueryUrl;
head.appendChild(script);
}
else {
callback();
}
})(arguments [0],arguments [arguments.length - 1]);
结果之前/之后:

I am using Python 2.7 and Selenium 2.44.
I want to automate drag and drop action in Selenium WD but according to other related posts Actions in HTML5 are not supported by Selenium yet. Is there any way to simulate drag and drop in Python?
Here is the code I tried:
driver = webdriver.Firefox()
driver.get("http://html5demos.com/drag")
target = driver.find_element_by_id("one")
source = driver.find_element_by_id("bin")
actionChains = ActionChains(driver)
actionChains.drag_and_drop(target, source).perform()
and it did not work.
Yes, HTML5 "drag&drop" is not currently supported by Selenium:
One of the suggested workarounds is to simulate HTML5 drag and drop via JavaScript:
- download
drag_and_drop_helper.js
- execute the script via
execute_script()
callingsimulateDragDrop()
function on asource
element passing thetarget
element as adropTarget
Sample code:
with open("drag_and_drop_helper.js") as f:
js = f.read()
driver.execute_script(js + "$('#one').simulateDragDrop({ dropTarget: '#bin'});")
The problem is that it won't work in your case "as is" since it requires jQuery
.
Now we need to figure out how to dynamically load jQuery. Thankfully, there is a solution.
Complete working example in Python:
from selenium import webdriver
jquery_url = "http://code.jquery.com/jquery-1.11.2.min.js"
driver = webdriver.Firefox()
driver.get("http://html5demos.com/drag")
driver.set_script_timeout(30)
# load jQuery helper
with open("jquery_load_helper.js") as f:
load_jquery_js = f.read()
# load drag and drop helper
with open("drag_and_drop_helper.js") as f:
drag_and_drop_js = f.read()
# load jQuery
driver.execute_async_script(load_jquery_js, jquery_url)
# perform drag&drop
driver.execute_script(drag_and_drop_js + "$('#one').simulateDragDrop({ dropTarget: '#bin'});")
where jquery_load_helper.js
contains:
/** dynamically load jQuery */
(function(jqueryUrl, callback) {
if (typeof jqueryUrl != 'string') {
jqueryUrl = 'https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js';
}
if (typeof jQuery == 'undefined') {
var script = document.createElement('script');
var head = document.getElementsByTagName('head')[0];
var done = false;
script.onload = script.onreadystatechange = (function() {
if (!done && (!this.readyState || this.readyState == 'loaded'
|| this.readyState == 'complete')) {
done = true;
script.onload = script.onreadystatechange = null;
head.removeChild(script);
callback();
}
});
script.src = jqueryUrl;
head.appendChild(script);
}
else {
callback();
}
})(arguments[0], arguments[arguments.length - 1]);
