How to restrict typing hyphen into extjs numberfield?

Question

Currently extjs numberfield is allowing '-' hyphen otherthan numbers into the field. how to restrict that from typing? if i give custom vtype validation it is checking only after i submit that.

Answer 1

use autoStripChars and remove hyphen from allowed in initComponent. corrected code below.

autoStripChars: true,
initComponent: function() {
    var me = this,
        allowed;

    me.callParent();

    me.setMinValue(me.minValue);
    me.setMaxValue(me.maxValue);

    // Build regexes for masking and stripping based on the configured options
    if (me.disableKeyFilter !== true) {
        allowed = me.baseChars + '';
        if (me.allowDecimals) {
            allowed += me.decimalSeparator;
        }
/* removed code
    if (me.minValue < 0) {
            allowed += '-';
        } 
*/
        allowed = Ext.String.escapeRegex(allowed);
        me.maskRe = new RegExp('[' + allowed + ']');
        if (me.autoStripChars) {
            me.stripCharsRe = new RegExp('[^' + allowed + ']', 'gi');
        }
    }
}
