1，最近测试中使用到了ajax的一个webedit自动填充的案例，想了好久，终于想到了一个解决的方案：
Set deviceReplay = CreateObject ("Mercury.DeviceReplay")
Browser("xx").Page("xx").WebEdit("xx").Object.focus
deviceReplay.SendString(str)
wait(10)
deviceReplay.PressKey(28)
2，第二种方法采用的是事件响应然后再敲击鼠标键盘，本人自己操作过，这个方法应该是比较好的，有一个论坛讨论了这个问题：
地址：http://www.advancedqtp.com/forums/index.php?action=printpage;topic=5594.0
代码设计如下：
dim str="s"
Set WshShell = CreateObject("WScript.Shell") Browser("testapp").Page("testapp").Frame("mIfm-3").WebEdit("dispatchOpName").Set str Browser("testapp").Page("testapp").Frame("mIfm-3").WebEdit("dispatchOpName").FireEvent "onclick" 'This simulate the mouse click event after value is set WshShell.SendKeys "{Down}" 'This displays the drop down list box 'wait 2 WshShell.SendKeys "{Down}" 'This hover over the first element in the list 'wait 2 WshShell.SendKeys "~" 'This selects the hovered element
3,采用的另外的方式；
3.1首先设置获得键盘的操作步骤，
Setting.WebPackage("ReplayType") = 2 'enable mouse operations Browser(X).Page(Y).WebEdit(Z).Set "ann"
Setting.WebPackage("ReplayType") = 1 'enable keyboard operations
WshShell.SendKeys "{DOWN}" 'To hit the down arrow n times you can use "{DOWN n}" 'To Select element WshShell.SendKeys "~"
4,其他的方式，暂时不写了。不过以上的已经可以解决大家所有的遇到的ajax的autocomplete的问题了。
5，如果以上的方案还不能够解决你的问题，可以尝试一下的一种方案，原始网页地址：
http://forums.testleaf.com/showthread.php?tid=633&pid=1324&language=settings
整理如下：
方法一：GetSuggestedOptionsArr(EditObj, PageObj, PartialText)
方法二：VerifyOptionsNumber(EditObj,PageObj, PartialText, ExpectedNumber)
方法三：IsInSuggestions(EditObj,PageObj, PartialText, SuggestedText)
方法四：SelectSuggestedOption(EditObj,PageObj, PartialText, SuggestedText)
方法五：TypeStringFromFirstToLast(EditObj, sText)
The GetSuggestedOptionsArr function simulates the "Auto Complete" behavior by setting a partial value to the search field and triggering the suggestion values retrieval by firing the "onkeyup" event. The Page.ChildObjects method is then used to get a collection of the returned values using a predefined description that uniquely identifies them:
set desc = Description.Create
desc("class").value = "cAutoComplete"
desc("micclass").value = "WebElement"
desc("html tag").value = "SPAN"
After the description is defined, it is used to capture a collection of the suggested possible values:
Set options = Browser("BrowserName").Page("PageName").ChildObjects (desc)
Example:
Create a reference to the Page object that contains the search edit field.
Set PageObj = Browser("Google").Page("Google")
Get an array with the possible search values
Dict = Browser("Google").Page("Google").WebEdit("q").GetSuggestedOptionsArr(PageObj,"a")
msgbox "The array contains " & UBound(Dict) & " suggested search strings."
Verify 10 suggestions were presented
result= Browser("Google").Page("Google").WebEdit("q").VerifyOptionsNumber(PageObj,"a",10)
msgbox "There are 10 suggested search strings: " & result
Check that "aol" is one of the returned suggested search values
bIsInSugg = Browser("Google").Page("Google").WebEdit("q").IsInSuggestions(PageObj,"a", "aol ")
msgbox "The value aol is in the suggested search strings: " & bIsInSugg
Get a vbNewLine delimited string of the suggested search options
txt = Browser("Google").Page("Google").WebEdit("q").GetSuggestedOptions(PageObj,"ca")
MsgBox txt
Enter the ab string character by character
Browser("Google").Page("Google").WebEdit("q").TypeStringFromFirstToLast "ab"
wait 2
6，完全靠模拟键盘的操作的方式：
