ajout de bouton de dojo datagrid

Je suis en train d'ajouter un bouton supprimer pour le Dojo Datagrid et j'ai actuellement le javascript suivant:

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>";
}

Chaque fois que je charge la page, je seulement obtenir une grille vide avec un message "désolé, une erreur s'est produite." Si je supprime le dernier champ avec le "getDelete" formateur, le contrôle datagrid remplit très bien. Je ne suis pas sûr de ce que je fais de mal de sorte que toute aide serait appréciée.

    Vous avez fait plusieurs erreurs dans votre getDelete fonction:

    1. magasin n'est pas défini, sans doute que vous vouliez dire jsonStore
    2. élément n'est pas objet de vous store. C'est la propriété, spécifié par "champ" (inc_number)

    Je pense que cela fonctionnera pour vous:

    function getDelete(item) {
  return "<button onclick=\"location.href='/report?command=delete&reportNo=" 
    + item + "'\">Delete</button>";
}
    Je vous remercie beaucoup pour l'aide, votre code a fonctionné parfaitement. Ouais, encore en train d'essayer d'obtenir le coup de dojo et de javascript. Merci encore

    Essayez ceci:

    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;
};

    Avec cette définition de la structure:

    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'}
        ]]
     }

    Alors:

    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();

    Et enfin, un peu de PHP sur le serveur:
    (Je n'ai pas d'abord besoin de tout cela, mais c'est tous disponibles en cas de besoin,
    ce code presque ne change jamais.)
