由 天大地大妈咪最大 提交于 2019-11-26 05:58:41
问题 I would like to manually apply searching to my jqGrid via JavaScript. I have tried a guide here, but can\'t seem to get it completely working. In the grid setup I have a column with name \'error_column\' that I would like to perform a search on looking for the string \'Test\'. Here is what I have so far: var filter = { \"field\": \"error_column\", \'oper\': \'eq\', \"data\": \'Test\' }; $(\"Grid2\").jqGrid(\'setGridParam\', { search: true, postData: { filters: filter} }) $(\"Grid2\").trigger(

问题 How can I run a batch file on the client side? An exe file? Just to open pre-installed program in client side? [Edit] Regarding ActiveX, I tried var activeXObj = new ActiveXObject(\"Shell.Application\"); activeXObj.ShellExecute(\"C:\\\\WINDOWS\\\\NOTEPAD.EXE\", \"\", \"\", \"open\", \"1\"); but this doesn\'t work.

How to get client date and time in ASP.NET?

由 試著忘記壹切 提交于 2019-11-26 03:57:21
问题 When I use DateTime.Now I get the date and time from the server point of view. Is there any way to get the client date and time in ASP.NET? 回答1: What I'd do is create a hidden input field and then wire a Javascript routine to the onsubmit event for the form. This routine would populate the hidden field with the time on the client machine. The hidden field can used with ASP.NET by using the HTML control "HtmlInputHidden" class. You just give you input control a runat="server" attribute like

In IndexedDB, is there a way to make a sorted compound query?

由 拥有回忆 提交于 2019-11-26 03:38:48
问题 Say a table has, name, ID, age, sex, education, etc. ID is the key and the table is also indexed for name, age and sex. I need all male students, older than 25, sorted by their names. This is easy in mySQL: SELECT * FROM table WHERE age > 25 AND sex = \"M\" ORDER BY name IndexDB allows creation of an index and orders the query based on that index. But it doesn\'t allow multiple queries like age and sex. I found a small library called queryIndexedDB (https://github.com/philikon/queryIndexedDB)

Is it worth hashing passwords on the client side

由 一个人想着一个人 提交于 2019-11-26 02:54:04
When I want to put a login system in place, I always compare the MD5 of the given password with its value in the users table on the server side. However, a friend of mine told me that a "clear" password could be sniffed by a network software. So my question is: is it a good idea to hash the password on the client side? Is it better than hashing it on the server side? Basically, your friend is right. But simply hashing the password on the client side is only just better than submitting it as plain text to the server. Someone, who can listen for your plain text passwords is certainly also able
