Question

An earlier question mentioned a method using the el config in order to make the browser remember passwords. Howewer, the el config no longer exists in ExtJS 4.1.

Now, what should I do?

Answer 1

I believe it should be contentEl instead of el but I do this another way. You can build the entire thing with ExtJS directly. The only twist is that Ext fields will be created with the autocomplete=off attribute by default, so I use a derived class to override that.

Ext.define('ACField', {
    extend: 'Ext.form.field.Text',

    initComponent: function() {
        Ext.each(this.fieldSubTpl, function(oneTpl, idx, allItems) {
            if (Ext.isString(oneTpl)) {
                allItems[idx] = oneTpl.replace('autocomplete="off"', 'autocomplete="on"');
            }
        });
        this.callParent(arguments);
    }
});

Ext.onReady(function() {
    new Ext.panel.Panel({
        renderTo: Ext.getBody(),
        width: 300,
        height: 100,
        autoEl: {
            tag: 'form',
            action: 'login.php',
            method: 'post'
        },  
        items: [
            new ACField({
                xtype: 'textfield',
                name: 'username',
                fieldLabel: 'Username'
            }), 
            new ACField({
                xtype: 'textfield',
                name: 'password',
                fieldLabel: 'Password',
                inputType: 'password'
            }), 
        ],
        buttons: [{
            xtype: 'button',
            text: 'Log in',
            type: 'submit',
            preventDefault: false
        }]
    });
});
