tasto aggiungendo al dojo datagrid

Question

Sto cercando di aggiungere un pulsante di eliminazione per il Dojo DataGrid e Al momento ho il seguente javascript:

function createGrid() { 
    gridTmp = new dojox.grid.DataGrid({ 
     store: jsonStore, 
     structure: [ 
      {name: "Report No", field:"inc_number"}, 
      {name: "Incident Date", field: "IncidentDate"}, 
      {name: "Report Date", field: "reportDate"}, 
      {name: "Location", field: "location"}, 
      {name: "Delete", field: "inc_number", formatter: getDelete} 
     ], 
     noDataMessage: 'No results returned' 
    }, "grids"); 

    return gridTmp; 
} 
dojo.addOnLoad(function() { 
    grid = createGrid(); 
    grid.startup(); 
}); 

function getDelete(item) { 
    return "<button onclick=\"location.href='/report?command=delete&reportNo=" 
      + store.getIdentity(item) + "'\">Delete</button>"; 
} 

Ogni volta che caricare la pagina ho solo una griglia vuota con un messaggio " Ci scusiamo, si é verificato un errore." Se rimuovo l'ultimo campo con il formattatore "getDelete", il datagrid viene compilato correttamente. Non sono sicuro di cosa sto facendo male, quindi qualsiasi aiuto sarebbe apprezzato.

Answer 1

Lei ha fatto diversi errori nella funzione getDelete:

1. negozio non è definito, probabilmente si intende jsonStore
2. articolo non è oggetto dalla memorizzare. E 'di proprietà, specificata da "campo" (inc_number)

Penso che questo sarà il lavoro per voi:

function getDelete(item) { 
    return "<button onclick=\"location.href='/report?command=delete&reportNo=" 
    + item + "'\">Delete</button>"; 
} 

Answer 2

Prova questo:

var buttonFormatter = function(inValue, rowId, cellId, cellField){ 
    if (inValue == 'Button_1') { 
    var new_button = new dijit.form.Button({ 
     label: 'Detail', showLabel: false, 
     iconClass: "dijitEditorIcon dijitEditorIconInsertOrderedList", 
     'class': 'gridButton'}); 
    new_button._destroyOnRemove = true; 
    return new_button; 
    } 
    else if (inValue == 'Button_2') { 
    var new_button = new dijit.form.Button({ 
     label: 'Detail', showLabel: false, 
     iconClass: "dijitEditorIcon dijitEditorIconRemoveFormat", 
     'class': 'gridButton'}); 
    new_button._destroyOnRemove = true; 
    return new_button; 
    } 
    else if (inValue == 'Button_3') { 
    var new_button = new dijit.form.Button({ 
     label: 'New', showLabel: false, 
     iconClass: "dijitEditorIcon dijitEditorIconSelectAll", 
     'class': 'gridButton'}); 
    new_button._destroyOnRemove = true; 
    return new_button; 
    } 
    else return null; 
}; 

Con questa definizione della struttura:

var structureDictionary = { 
      ... 
      ... 
    'schoolA': [[ 
     { name: ' ', field: 'Button_1', width: '22px', 
      styles: 'margin:0px; padding:0px; text-align: left;', 
      formatter: buttonFormatter}, 
     { name: ' ', field: 'Button_3', width: '22px', 
      styles: 'margin:0px; padding:0px; text-align: left;', 
      formatter: buttonFormatter}, 
     { name: 'School', field: 'school_name', width: '160px'}, 
     { name: 'District', field: 'district_name', width: '160px'}, 
     { name: 'Address', field: 'address', width: '100%'}, 
     { name: 'City', field: 'city', width: '120px'}, 
     { name: 'State', field: 'state', width: '40px'}, 
     { name: 'Zip', field: 'zip', width: '40px'}, 
     { name: 'VT', field: 'vt_account', width: '20px'} 
     ]] 
    } 

Quindi:

var newStore = new dojo.data.ItemFileReadStore({url: DataURL + fragment}); 
// May need to force a load: newStore._forceLoad(); 
Grid.setStructure(structureDictionary['schoolA']); 
Grid.setStore(newStore); 
Grid.selection.clear(); 

E finalmente un po 'di PHP sul server: (. Io non inizialmente bisogno di tutto questo ma è tutto a disposizione in caso di necessità, questo codice quasi mai cambia)
