javascript - How to write a custom formatter for Google DataTables (for use on visualisation api) -

-

I am looking to format my data in which I change the numbers with the mouse.

As far as I can tell that Google does not currently have the format to do this:

A brief mention in the documentation about custom formats But I can not find any such document

Can anyone tell me in the right direction?

There is a similar question on stack overflow:. However, the question was used only by using the built-in formats (which I think that I can not do).

I do not think make you able to do the current format as you wish You can, but you will be able to make your own format easily enough. I put the iconFormatter together for a sample - it can be adjusted to whatever you need, to do it. 

  & lt; Html xmlns = "http://www.w3.org/1999/xhtml" & gt; & Lt; Top & gt; & Lt; Script type = "text / javascript" src = "http://www.google.com/jsapi" & gt; & Lt; / Script & gt; & Lt; Script type = "text / javascript" & gt; Google.load ('Visualization', '1', {packages: ['table']}); & Lt; / Script & gt; & Lt; Script type = "text / javascript" & gt; / ** * Givis icon format * @PRAM {Object & lt; Number, string & gt;} icon URI * / var iconFormatter = map for maps (mapMap) {this.iconMap = iconMap; } / ** * To formattify a gviz datatyal column * @the ultimate {object} DT Datatable * @param {number} column index number * / iconFormatter.prototype.format = function (dt, column) {for (var i = 0; I & lt; dt.getNumberOfRows (); i ++) {var formatted value = this.iconMap [dt.getValue (i, column)]; Var html string = "& lt; img src =" + valued value "/>"; Dt.setFormattedValue (i, column, html string); // built-in value consol.log protected (dt.getValue (i, column)); }} & Lt; / Script & gt; & Lt; Script & gt; Function drawVisualization () {// Create and populate data table. Var data = new google.visualization.DataTable (); Data.addColumn ('string', 'name'); Data.addColumn ('number', 'height'); Data.addRows (3); Data.setCell (0, 0, 'Tong Anne Mu'); Data.setCell (1, 0, 'Huang ange fa'); Data.setCell (2, 0, 'Teng NU'); Data.setCell (0, 1, 174); Data.setCell (1, 1, 523); Data.setCell (2, 1, 86); Var iconmap = {174: "http://farm1.static.flickr.com/76/buddyicons/63892905@N00.jpg?1149480603", 523: "http://farm1.static.flickr.com/28/buddyicons /20741728@N00.jpg?1129271399 ", 86:" http://farm3.static.flickr.com/2698/buddyicons/70986564@N00.jpg?1303489082 "// other numbers} // Create and draw visualization. Visualization = new google.visualization.Table (document.getElementById ('table')); // apply to our format, such as normal var format = new iconformer (iconmap); Formatter.format (data, 1); // Allow html, like any html formatter will require visualization.draw (data, {allowHtml: true}); } Google.setOnLoad callback (draft); & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Div id = "table" & gt; & Lt; / Div & gt; & Lt; / Body & gt; & Lt; / Html & gt;   
 Hope that helps.

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...

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...
