扩展ExtJS numberfield支持千位分隔符(一)

在项目需求中,需要把金额数据

Ext.ux.NuberFiledFormat=Ext.extend(Ext.form.NumberField, {
    baseChars: "0123456789,",
    setValue: function(v){
        v = typeof v == 'number' ? v : String(v).replace(this.decimalSeparator, ".").replace(/,/g, "");
         v = isNaN(v) ? '' : rendererZhMoney(v);
        
        //Ext.util.Format.number(this.fixPrecision(String(v)), "0,000,000.00");此为ext 4.0 
            this.setRawValue(v);
        return Ext.form.NumberField.superclass.setValue.call(this, v);
    },
   /* getValue:function(){
    	//alert((String(Ext.form.NumberField.superclass.getValue.call(this)).replace(",","")));
    	return (String(Ext.form.NumberField.superclass.getValue.call(this)).replace(",",""));
    },
    */
    fixPrecision: function(value){
        var nan = isNaN(value);
        if (!this.allowDecimals || this.decimalPrecision == -1 || nan || !value) {
            return nan ? '' : value;
        }
        return parseFloat(value).toFixed(this.decimalPrecision);
    },
    validateValue: function(value){
        if (!Ext.form.NumberField.superclass.validateValue.call(this, value)) {
            return false;
        }
        if (value.length < 1) { // if it's blank and textfield didn't flag it then it's valid
            return true;
        }
        value = String(value).replace(this.decimalSeparator, ".").replace(/,/g, "");
        if (isNaN(value)) {
            this.markInvalid(String.format(this.nanText, value));
            return false;
        }
        var num = this.parseValue(value);
        if (num < this.minValue) {
            this.markInvalid(String.format(this.minText, this.minValue));
            return false;
        }
        if (num > this.maxValue) {
            this.markInvalid(String.format(this.maxText, this.maxValue));
            return false;
        }
        return true;
    },
    parseValue: function(value){
        value = parseFloat(String(value).replace(this.decimalSeparator, ".").replace(/,/g, ""));
        return isNaN(value) ? '' : value;
    }
});
//注册扩展后的数字控件
Ext.reg('numberFieldFormat', Ext.ux.NuberFiledFormat);

注意:
上面代码中rendererZhMoney(v);js方法请参照

使用示例
//在控件中指定xtype即可
 xtype:"numberFieldFormat"


显示效果


好了,显示问题解决了,但在提交数据时,会把格式化后的数据提交,包含千分符,
关于处理提交问题,下一篇再讨论
