Question

I want to add a string at the end of a jquery object. Something like this:

var mytable = $("<table><tbody><tr><td>");
mytable.after("Test</td></tr></tbody></table>");

I tried with that too

mytable += "Test</td></tr></tbody></table>";

Doesn’t work either.

jQuery doesn’t work that way. When you’re dealing with elements in jQuery they are always valid. If it can’t validate it, it won’t add it. I tried your example and jQuery completed the invalid HTML:

var mytable = $("<table><tbody><tr><td>");    
// mytable is equal to $("<table><tbody><tr><td></td></tr></tbody></table>");

If you’re looking to add a new cell to your table, you could select the required element (i.e. the tr) and then use the append method

mytable.find("tr").append("<td>New cell</td>");

Of course, you can add two strings together and put them in a jQuery object as long as they join to make valid HTML

var string1 = "<table><tbody><tr><td>First half and";
    string1 = " second half</td></tr></tbody></table>";

mytable = $(string1 + string2);
