jquery - How can I pass a row as parameter to javascript? -

-

I want to get one line information to show in the tooltip. For example: 

  & lt; Html & gt; & Lt; Table style = "width: 100%" & gt; & Lt; TR & gt; & Lt; TD & gt; Jill & lt; / TD & gt; & Lt; Td onmouseover = "loadtooltip (parameter)" & gt; Smith & lt; / Td> & Lt; TD & gt; 50 & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; TD & gt; Eve & lt; / TD & gt; & Lt; Td onmouseover = "loaderolite (parameter)" & gt; Jackson & lt; / Td> & Lt; TD & gt; 94 & lt; / TD & gt; & Lt; / TR & gt; & Lt; / Table & gt; & Lt; Html & gt;

Therefore, when I put the mouse on the line, then I need the contents of the other columns.

Thx in advance

You have tagged your question with jQuery, so I'm assuming that a jQuery solution is acceptable is. First of all, do not inline your event operators, this is a bad form, instead, hook your event handlers using .on instead. I've added a class to identify td , you want to add the roll to a little easier. So in the handler, this will refer to an event that receives this event and you can use $ (this). Parent () this is the parent tr . 

 
  & Lt; script src = "https: //ajax.googleapis. Com / ajax / libs / jquery / 2.1.1 / jquery.min.js "& gt; & lt; / script> gt; & lt; html & gt; table style =" width: 100% "& gt; ; & Lt; tr & gt; & gt; TD & gt; Jill & lt; / td & gt; & lt; td class = "rollable" & gt; Smith & lt; / td & gt; & lt; TD> 50   gt; & lt; td> 94 & lt; / td & gt; & lt; / tr & gt; & lt; / table & gt; Lt; html & gt;

Edit: Your comment shows that you actually 

 
  & lt; Script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js" & gt; & Lt; / Script & gt; & Lt; Html & gt; & Lt; Table style = "width: 100%" & gt; & Lt; TR & gt; & Lt; TD & gt; Jill & lt; / TD & gt; & Lt; Td square = "rollable" & gt; Smith & lt; / Td> & Lt; TD & gt; 50 & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; TD & gt; Eve & lt; / TD & gt; & Lt; Td square = "rollable" & gt; Jackson & lt; / Td> & Lt; TD & gt; 94 & lt; / TD & gt; & Lt; / TR & gt; & Lt; / Table & gt; & Lt; Html & gt;

javascript - data.match(var) not working it seems -

-
OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
