jquery - xmlhttp.send() within .each() sends only the last record -

-

I'm trying to teach myself some php and Ajax for a pet startup project - $$$ $ someone Real technical man :-) Anyway, this is the background. I have selected a data in the HTML table, when an submitted function is called in the update. To select the selected record (radio button) I loop through the table and call them the update line file, assign a row and loop through each line and send the record to add to the database when I have If there is a JavaScript alert statement then all records are added to the database. But if I comment the warning then only the final record is added. I have tried to add 3 seconds, 5 seconds delay in the loop.

Here is the code snippet - some variables are set out of this loop and there is no problem with the values. $ row.each (function () {var $ rowcells = $ (this) .find ('td'); // Divide the entire row into columns var name = $ rowcells Eq (0) .text (); // Name of the selected relationship name = $ rowcells.eq (1). Child (). Val (); // Relationship with person // warning ("I was here" Name); // When this alert is uncommented xmlhttp.open ("post", "profileupdate.php", true), all records are added; xmlhttp.setRequestHeader ("content type", "application / x-www-form - urlencoded "); Xmlhttp.send (" type = "+ type +" & amp; userid = "+ userid +" and userrelid = "+ userrelid +" and relationtype = "+ relationtype +" and timer Eat = "+ timeouttext";});

I think connecting one at a time would be expensive on DB's performance. I should change that argument anyway but in the interim it would be nice to know what is happening here. N

You are sending HTTP request server asynchronous ('true' second parameter xmlhttp.open). This means that the next item in the row overrides the previous one.

You can try:

  • using multiple xmlhttp objects (for each element of the array)
  • as the second parameter Use the 'false'
  • In the third case, only after the last one has completed (in 'onreadystatechange' handler) to process the next element

    Can not use every 'iterator.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
