forms - Fetching HTML input from text and drop down menu in Javascript? -

-

I want to give users two input mechanisms - using the element, text entry and drop down menu. The input value is taken in javascript.

I can work on every method, but not together.

This is probably the fundamental question, but can someone else tell me what is the cost for each input for event handlers as well as this input? 

  & lt; Form name = "myform" onsubmit = "return userInput ()" & gt; & Lt; Id = "myVal" onchange = "userInput ()" onsubmit = "return user input ()" & gt; & Lt; Options & gt; Select a country & lt; / Options & gt; & Lt; Option value = "all countries" & gt; All countries & lt; / Options & gt; & Lt; Option value = "Austriaia" & gt; Austria & lt; / Options & gt; & Lt; Option value = "Korea" & gt; Korea & lt; / Options & gt; & Lt; Option value = "Austria" & gt; Austria & lt; / Options & gt; & Lt; Option value = "United States" & gt; United States & lt; / Options & gt; & Lt; Option value = "Japan" & gt; Japan & lt; / Options & gt; & Lt; Option value = "Canada" & gt; Canada & lt; / Options & gt; & Lt; Option value = "India" & gt; India & lt; / Options & gt; & Lt; / Select & gt; & Lt ;! - & lt; Input name = "submit" type = "submit" value = "add to list" & gt; - & gt; & Lt; Input type = "text" id = "myVal" placeholder = "add some text & hellip;" & Gt; & Lt; / Form & gt; // Javascript code where I'm bringing user input Function user input (event) {userinput = document.getElementById ("myVal"). Value // console.log (userinput) // console.log (document.getElementById ("myVal"). Value) //draw(document.getElementById ("MyVal"). Value) d3.select ('svg'). Remove (); Main(); Console.log ("called main") // Draw (document.getElementById ("myVal"). Value) return false; } 
 
 Both your selected element and your text input element have the same ID. Make them unique and make a call for each element in your JS. Also, get rid of an onsubmit event handler feature in your selected element.

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
