I have to show a warning box when click on the button but nothing happens I'm not sure that one thing If I want to unify the identifier var in the signature of the function, then function popup (var message) 

   & Lt; Title & gt; Trial ... & lt; / Title & gt; & Lt; Script type = "text / javascript" & gt; Function popup (var message) {var a = 5 var 2 = 3 warning (message) if (one * two == 15) {warning ("you were right")} other {alerts ("you were wrong")}} & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; Hello, I'm here & Lt; Br / & gt; & Lt; Input type = "button" value = "click here" onclick = "popup" (this is my message ")" /> & lt; / body & gt; & lt; / html> gt;   
 IE returns the following error details: Webpage error description

 Message: Object Expected Line: 25 characters: 1 Code: 0 URI: File: /// C: / U / UJX 9 9 / e / desktop / jscripttest.html  
 I'm not sure how to find it in Firefox.  
 Edit: On the small error icon below IE Instead of clicking, there is a better way of javascript errors?   
 
 
 You have the  var before the function parameter  can not be.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others.
