Spring controller - send html as response -

-

I have a jsp page loaded with products and add links against it. I am trying to show the cart in a div in the same page. I want to send html as feedback. This is what I have done. This is just the string & lt; Div & gt; Output & lt; / Div & gt; returns. Someone can show me how I should do it.

controller 

  @RequestMapping (value = "/ addtocart {id}"), produces = "text / plain; charset = UTF -8 ") @ Risponsbodi public string Adtoart (@ Path variable (" ID ") Int ID, @ model attribute (" carriage ") train carts, models) {product product = Utpadsewa. ProductivityIID; If (product! = Null) {cartline line = new cartline (); Line.setProduct (product); Line.setQuantity (1); ProductService.updateProduct (product); } Return "
 Output "; }

JSP 

  & lt; Td> & Lt; An id = "demo4" href = "addtocart $ {product. Id}" & gt; Add to Cart & lt; / A & gt; & Lt; / TD & gt; Click $ ( '# Demo4') to (function () {$. Ajax ({url: '/ addtocart {id}', datatype 'Jason', content type "text / html", type: 'GET' Data: {Id: id}, success: function (response) {$ ('# output'). Html (response);}})}}; & Lt; Div id = "output" style = "display: none" & gt; & Lt; H2 & gt; Cart content (s): & lt; / H2 & gt; & Lt; / Div & gt;

I use the scene as well as the side of a different page on the AJAX call I am However, whatever you are asking for, just to produce your production = "text / plain; described = UTF-8" 

  output = "text There are many other aspects that appear to be incorrect, not related to Spring MVC, so even with the product You still have to make some corrections to get what you are expecting   
 It will be something like this, if it works Not closer to more than, then it will not be completely 
 
   
 
 Rename 
   @RequestMapping (value = "/ addtocart {productId}", output = "text / plain; charset = UTF-8") Public String Adtart (@Path Variable ("Product ID") Ent Product ID, @ Model Attribute ("Cart") Cart Cart, Model Model)

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

Before I continue to get a jQuery .each loop to wait for user input There is a problem in repeatedly repeating This is my code (I have commented on what I would like to do): & lt; Html xmlns = "http://www.w3.org/1999/xhtml" & gt; & Lt; Top & gt; & Lt; Link rel = "stylesheet" type = "text / css" href = "common_components.css" /> & Lt; Meta http-equiv = "content-type" content = "text / html; charset = UTF-8" /> & Lt; Link rel = "stylesheet" href = "slider.css" & gt; & Lt ;?
