请告诉我，如何使用两种类型的分隔符数字输入字段？您只能使用一种标准方法，但在不同的键盘布局中，需要使用另一种，将数据保持为一种格式，即“。”

输入：10,789 或 10.789 保存：10.789

我使用Ext.form.NumberField来编辑积分字段。

我的部分代码：

var editor = new Ext.ux.grid.RowEditor({
    saveText: LANG['update'],
    listeners: {
        afteredit: function(object, changes, r, rowIndex) {
            Ext.MessageBox.alert(LANG['alert_info'], LANG['memory']); }

        }
    }
});

 var userGrid = new Ext.grid.GridPanel({
        id: 'status-form',
        region:'center',
        margins: '5 5 5 5',
        store: Gstore,
        iconCls: 'icon-grid',
        plugins: [editor, summary],

        cm: new Ext.grid.ColumnModel([

            {header: "ID", width: 30, sortable: true, dataIndex: 'idb', renderer: formatID},
            {xtype: 'datecolumn', header: LANG['date'], width: 70, sortable: true, dataIndex: 'date', 
                groupRenderer: Ext.util.Format.dateRenderer('M Y'), 
                format: 'd/m/Y',
                editor: new Ext.form.DateField({
                    value: (new Date()).format('d/m/Y'), 
                    //format: 'd/m/Y',
                    minValue: '01/01/2010',
                    //minText: 'Please Check Correct Data',
                    maxValue: (new Date()).format('d/m/Y'),
                    editable: false
                })
            },

                }
            },

                editor: new Ext.form.NumberField({

我用简单的方法实现了这一点。我的方法是启用数字字段的按键事件并检查按下的键是否为“，”而不是添加“。” 去估价。那就是执行；

Ext.create('Ext.form.Panel', {
title: 'On The Wall',
width: 300,
bodyPadding: 10,
renderTo: Ext.getBody(),
items: [{
    xtype: 'numberfield',
    anchor: '100%',
    name: 'bottles',
    fieldLabel: 'Bottles of Beer',
    enableKeyEvents : true,
    value: 99,
    maxValue: 99,
    minValue: 0,
    listeners : {
        keypress : function(view, e){
                if(e.getKey() == 44)
                    view.setRawValue(view.getRawValue() +'.');
           }
        }
    }]
});

解决方案在这里找到：http: //habrahabr.ru/post/137966/（俄罗斯语言）因为已经看到版本> 4.0的解决方案，我不得不更改代码，替换标准的JS函数。 Vykladyvayu 它在这里，也许有人会需要：

从页面头部开始连接 сursor.js

// Author: Diego Perini <dperini@nwbox.com>
var sb = new Array(
    'leftbox', 'rightbox', 'scrollLeft', 'scrollRight', 
    'caretPos', 'maxLength', 'textLength', 'availLength',
    'beforeCaret', 'afterCaret', 'selectedText'
)

var leftbox = {};
var rightbox = {};
var scrollLeft = {};
var scrollRight = {};
var caretPos = {};
var maxLength = {};
var textLength = {};
var availLength = {};
var beforeCaret = {};
var afterCaret = {};
var selectedText = {};

/*
for (var i in sb) {
    var v = '"var '+sb[i]+' = {}"';
    eval(v);
}
*/

var os = 0
var oe = 0
function update(o) {
    var t = o.value, s = getSelectionStart(o), e = getSelectionEnd(o)
    if (s == os && e == oe) return
    caretPos.firstChild.nodeValue = s
    maxLength.firstChild.nodeValue = o.getAttribute('maxLength')
    textLength.firstChild.nodeValue = t.length
    availLength.firstChild.nodeValue = o.getAttribute('maxLength') - t.length
    afterCaret.firstChild.nodeValue = t.substring(s).replace(/ /g, '\xa0') || '\xa0'
    beforeCaret.firstChild.nodeValue = t.substring(0, s).replace(/ /g, '\xa0') || '\xa0'
    selectedText.firstChild.nodeValue = t.substring(s, e).replace(/ /g, '\xa0') || '\xa0'
    rightbox.value = scrollRight.firstChild.nodeValue = t.substring(s).replace(/ /g, '\xa0') || '\xa0'
    leftbox.value = scrollLeft.firstChild.nodeValue = t.substring(0, s).replace(/ /g, '\xa0') || '\xa0'
    os = s
    oe = e
    return true
}

function setup() {
    for (var i in sb) eval(sb[i] + ' = document.getElementById(sb[i])')
    update(document.getElementById('textbox'))
}

function getSelectionStart(o) {
    if (o.createTextRange) {
        var r = document.selection.createRange().duplicate()
        r.moveEnd('character', o.value.length)
        if (r.text == '') return o.value.length
        return o.value.lastIndexOf(r.text)
    } else return o.selectionStart
}

function getSelectionEnd(o) {
    if (o.createTextRange) {
        var r = document.selection.createRange().duplicate()
        r.moveStart('character', -o.value.length)
        return r.text.length
    } else return o.selectionEnd
}

并连接插件：

Ext.ns('Ext.ux.form');

/**

        Ext.ux.form.NumberInputFilter.superclass.initComponent.call(this);
    },
    init : function(field) {
        if (!(field && field.isXType('numberfield'))) {
            return;
        }
        Ext.apply(field, {

                var start = getSelectionStart(el);
                var end = getSelectionEnd(el);
                if (start != end) {
                    // delete the selected text from the expected values
                    raw = raw.substring(0, start) + raw.substring(end);
                }
                if (Ext.isEmpty(raw)) {
                    return (newChar == this.decimalSeparator || (this.minValue < 0) && newChar == '-') || newChar.search('/^\d$/');

        field.updateDecimalPrecision(field.decimalPrecision, true);
    }
});
Ext.preg('numberinputfilter', Ext.ux.form.NumberInputFilter);

使用任何分隔符，我们喜欢在数字字段中使用，只需列出它们：

.....
            {header: LANG['lenght'], width: 60, sortable: true, dataIndex: 'lenght', renderer: formatKM, align: 'center', 
                summaryType: 'sum',
                summaryRenderer: Ext.util.Format.cifres2,
                editor: new Ext.form.NumberField({
                    allowNegative: false,
                    decimalPrecision: 2,
                    plugins: new Ext.ux.form.NumberInputFilter({
allowedDecimalSeparators : ',.-'
}),
                    maxValue: 1000,
                    allowBlank: false
                })

            },
.....

我在我的项目中使用了它，但我不知道它是否符合您的要求。

首先，检查它的数字和有“。”的值。然后根据这个条件设置适当的值。如果没有“。” 在值中然后调用替换函数。

value.match(/^[0-9]+\.?[0-9]*$/) ? Number(value) : Number((value.replace(',', '.')));
