javascript - Value of a Drag and Drop with the click of a button -


I am trying to create a quiz that registers the pulling and dropping actions, so if you have the right 'squares' Drag it to the right 'box' and then click the Submit button, the result is displayed.

The problem I have is: How would Javascript be understood which section is pressed after which box is pressed? 

  & lt ;! DOCTYPE HTML & gt; & Lt; Html & gt; & Lt; Top & gt; & Lt; Style & gt; # Div1, # div2 {float: left; Width: 50px; Height: 50px; Margin: 3px;} # div3, # div4 {float: left; Width: 56px; Height: 56px; Margin: 3px;} & lt; / Style & gt; & Lt; Script & gt; Function allowDrop (ev) {ev.preventDefault ()}} drag the function (ev) {ev.dataTransfer.setData ("text", ev.target.id);} function drop (ev) {ev.preventDefault (); Var data = ev.dataTransfer.getData ("text"); Ev.target.appendChild (document.getElementById); } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Center & gt; & Lt; Div style = "position: full; left: 50px; top: 0px;" & Gt; & Lt; Div id = "div1" style = "background: # 00f" draggable = "true" ondragstart = "drag (event)" id = "drag1" & gt; & Lt; / Div & gt; & Lt; Div id = "div2" style = "background: # f00" draggable = "true" ondragstart = "drag (event)" id = "drag2" & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div style = "position: full; left: 40px; top: 100px;" & Gt; & Lt; Div id = "div3" style = "border: 3px solid # 00f" ondrop = "drop (event)" ondragover = "allowdrop (event)" & gt; & Lt; / Div & gt; & Lt; Div id = "div4" style = "border: 3px solid # f00" ondrop = "drop (event)" ondragover = "allowdrop (event)" & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div style = "position: full; left: 75px; top: 200px;" & Gt; & Lt; Button type = "button" class = "myBttn" onclick = "doSomething ()" & gt; Submit & lt; / Button & gt; & Lt; / Div & gt; & Lt; / Center & gt; & Lt; / Body & gt; & Lt; / Html & gt;  
 
 What if you want to drag and drop events Use them to compare. Compare them.  
    
  & lt; Div style = "position: full; left: 50px; top: 0px;" & Gt; & Lt; Div id = "sourceB" class = "b" dragable = "true" ondragstart = "drag (event)" data-target-id = "tb" & gt; & Lt; / Div & gt; & Lt; Div id = "sourceRed" class = "r" dragable = "true" ondragstart = "drag (event)" data-target-id = "tr" & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div style = "position: full; left: 40px; top: 100px;" & Gt; & Lt; Div id = "tb" class = "tb" ondrop = "drop (event)" ondragover = "allowdrop (event)" data-match = "sourceb" & gt; & Lt; / Div & gt; & Lt; Div id = "tr" class = "tr" ondrop = "drop (event)" ondragover = "allowdrop (event)" data-match = "source r" & gt; & Lt; / Div & gt; & Lt; / Div & gt;   
 This is Javascript  
  var droppedEmentId; Function drag (ev) {ev.dataTransfer.setData ("text", ev.target.id); Console.log ("ev.target.id =", ev.target.id); Left elementid = ev.target.id; } Function drop (ev) {ev.preventDefault (); Var target element = document. GetElementById (ev.srcElement.id); Var dropTarget = targetElement.getAttribute ("data-match"); Console.log ("ev.srcElement.id =", ev.srcElement.id); If (droppedElementId == dropTarget) {console.log ("dropTarget =" + dropTarget); Console.log ("droppedElementId =" + ElementI has been dropped); }; Var data = ev.dataTransfer.getData ("text"); Ev.target.appendChild (document.getElementById); }   
 This is just a quick shot and the cross browser has not been tested. This - it's probably.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
