javascript - How do I make elements that are generated after page load (ajax) become draggable? -

-

I have a page that, through an AJAX call, different php scripts are populated in every 2000ms. When the user checks a checkbox, the update interval stops and all items in the div are required to be dragged. If I do this without the update interval, but once I loose the items to load the div again, how can I make their draggable assets loose? 

  & lt; SCRIPT LANGUAGE = "JavaScript" & gt; $ (Window) .load (function () {getScreen ();}); Var editMode = false; Var intervalid = window.setInterval (getScreen, 2000); Function getScreen () {if (window.XMLHttpRequest) {// code for IE7 +, Firefox, Chrome, Opera, Safari xmlhttp = new XMLHttpRequest (); } Else {// code for IE6, IE5 xmlhttp = new ActiveXObject ("Microsoft.XMLHTTP"); } Xmlhttp.onreadystatechange = function () {if (xmlhttp.readyState == 4 & xmlhttp.status == 200} {document.getElementById ("Refresh"). InnerHTML = xmlhttp.responseText;}} Xmlhttp.open ( "POST", "getScreen.php? Sid =" + & lt ;? php echo $ sid;; & gt ;, true); xmlhttp.send ();} function on edit mode (CB) {if (cb. Checked) {editMode = true; $ ('item') Dragable ('enabled'); window.clearInterval (intervalId);} and {editMode = false; $ ('. Item') Dragable ('disabled '); IntervalID = window.SetInterver (Milltex, 2000);}}   gt; body & gt; & lt; div id = "content" & gt; Gt; & lt; div class = "post" & gt; div id = "refresh" & gt; & lt; / div & gt; & lt; / div & gt; Lt; / div>    
 
 
 After you overwrite you in Ajax Callback Should make the item dragable / non-dragable Container HTML Once the HTML is overwritten, any attached domain listeners are lost.  
  var refresh = $ ('# refresh'); Refresh.html (xmlhttp.responseText); $ ('. Item', refresh) Drug ('Enabled');   
 And yes, as Peeders Starlar said, there are excellent Ajax features in jQuery  the method does exactly what you do ??? Loads HTML in a container.   
 In addition, you will ensure  setInterval  inside  setTimeout  > Ajax callback  this smooth update experience .  
  var postData = {sid: & lt ;? = Sid? & Gt; }; Var container = $ ('# refresh'); Var ajax callback = function (data) {container.html (data); Var item = $ ('. Item', container); If (editMode) {items.draggable ('enabled'); } And {items.draggable ('disabled'); SetTimeout (getScreen, 2000); }}; Function getScreen () {$ .post ('/ getScreen.php', PostData, Ajax Callback); } GetScreen ();

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
