javascript - ExtJs 5: Loading Mask in GridView -

-

My exclusions 5 app has a floating window, which has a grid, I have hidden column in Gird, where I have a user-image Display me To avoid waste traffic, images are only received by an additional store when the user sets the column visible. The code is loaded into the "pre-existing" event to load the images and when the loading is complete, the grid will be refreshed.

Because shipments can take a few seconds, I want to use the mask overlay component. But Wen I want to add a mask, the following error occure: 

  Uncustom TypeError: Can not set property 'component' of the faucet Renderable.js? _dc = 1414507483010: 938 I think the reason for this problem is an event or an anonymous function  
  listeners: {first cadre: function (column, metadata) ) {Var store = Ext.getStore ('Member ImageStore'); Var grid = this.up ('grid'); Var view = grid.getView (); View.setMasked (right); Store.loadMemberImages ({Scope: Grid, Callback: Function (Records, Operations, Success) {If (success!) {Return;} var view = this.getView (); see refresh ();}}); }}  
 
 I have already tried various function parameters on different components. But nothing worked for me, can anyone show me an alternative solution to solve the problem?

Try calling call grid.mask ('Loading ...' ) And of course, grid.unmask () , when done.

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
