Ext 四舍五入
Extjs让显示的Double类型的数据保留2位小数1. Ext.util.Format.round(value, precision); //
precision指精确位数。没有四舍五入
2.四舍五入
Ext.override(Ext.form.NumberField, {
setValue : function(v){
v = typeof v == 'number' ? v : String(v).replace(this.decimalSeparator, ".");
v = isNaN(v) ? '' : String(v).replace(".", this.decimalSeparator);
return Ext.form.NumberField.superclass.setValue.call(this, v);
},
fixPrecision : function(value){
var nan = isNaN(value);
if(!this.allowDecimals || this.decimalPrecision == -1 || nan || !value){
return nan ? '' : value;
}
return parseFloat(value).toFixed(this.decimalPrecision);
}
})
