如何让网格中的文本框小部件工作属性



我使用格式化程序在网格单元中放置了一个文本框小部件。但是,我无法移动光标,也无法在文本框中选择文本。

例如。http://jsfiddle.net/g33m9/69/

有人知道怎么解决这个问题吗?

感谢

您需要将列设置为"可编辑",以便网格组件知道如何处理按键事件。因此,需要对布局进行修改

来自

var layout = [[
        {name: 'Column 1', field: 'col1'},
        {name: 'Column 2', field: 'col2', width:'200px', formatter: func}
    ]]; 

var layout = [[
        {name: 'Column 1', field: 'col1'},
        {name: 'Column 2', field: 'col2', width:'200px', formatter: func, editable: true}
    ]]; 

双击可激活编辑状态。

现在,OP希望它成为一个完全膨胀的小部件,以可编辑状态弹出。为了使其可扩展到任意数量的行/列,我将其限制为编辑状态,以便该值仅显示文本,但双击后将弹出FilteringSelect。dijit小部件ValidationTextBox也遵循同样的原理。

目前(1.7.2)可能的细胞类型有:dojox.grid.cells.Booldojox.grid.cells.ComboBoxdojox.grid.cells.DateTextBoxdojox.grid.cells.选择

自定义dojox.grid cellType小部件的示例-半编程

第一步-创建一些数据

var i = 0,
data = {
    identifier: 'id',
    items: [
      { id: i, value: 'val'+i++},
      { id: i, value: 'val'+i++},
      { id: i, value: 'val'+i++},
      { id: i, value: 'val'+i++}
    ]
},
// The item label which holds visible value and which holds the value to represent
searchAttr = 'value',
valueAttr = data.identifier,
// The store to use for select widget
store = new dojo.data.ItemFileReadStore({ data: data }),
// And the options, reassembling the valid options we will present in dropdown
// Used when cellType is dojox.grid.cells.Select to name the allowable options
options = [];
dojo.forEach(data.items, function(it) { options.push(it[searchAttr])});

技巧部分-定义单元格类型

让我们扩展现有的dojox.grid.cells.Cell,它有两个关键功能-编辑状态格式化程序和默认格式化程序。默认情况会很好。最后但同样重要的是,我们将覆盖"_finish"函数,尽管它也允许Cell处理自己的定义。

var whenIdle = function( /*inContext, inMethod, args ...*/ ) {
    setTimeout(dojo.hitch.apply(dojo, arguments), 0);
};
var FilteringSelectCell = declare("dojox.grid.cells.FilteringSelect", [dojox.grid.cells.Cell], {
    options: null,
    values: null,
    _destroyOnRemove: true,
    constructor: function(inCell){
        this.values = this.values || this.options;
    },
    selectMarkupFactory: function(cellData, rowIndex) {
        var h = ['<select data-dojo-type="dijit.form.FilteringSelect" id="deleteme' + rowIndex + '" name="foo">'];
        for (var i = 0, o, v;
        ((o = this.options[i]) !== undefined) && ((v = this.values[i]) !== undefined); i++) {
            v = v.replace ? v.replace(/&/g, '&amp;').replace(/</g, '&lt;') : v;
            o = o.replace ? o.replace(/&/g, '&amp;').replace(/</g, '&lt;') : o;
            h.push("<option", (cellData == v ? ' selected' : ''), ' value="' + v + '"', ">", o, "</option>");
        }
        h.push('</select>');
        return h;
    },
    textMarkupFactory: function(cellData, rowIndex) {
        return ['<input class="dojoxGridInput" id="deleteme' + rowIndex + '" data-dojo-type="dijit.form.ValidationTextBox" type="text" value="' + cellData + '">']
    },
    // @override
    formatEditing: function(cellData, rowIndex) {
        this.needFormatNode(cellData, rowIndex);
        var h = (cellData == "W1")
            ? this.textMarkupFactory(cellData, rowIndex)
            : this.selectMarkupFactory(cellData, rowIndex);
        // a slight hack here, i had no time to figure out when the html would actually be inserted to the '<td>' so.. Use 'debugger' statement and track function to hook into
        whenIdle(function() {
            dojo.parser.parse(dojo.byId('deleteme' + rowIndex).parentNode);
            var w = dijit.byId('deleteme' + rowIndex);
            w.focus()
        });
        return h.join('');
    },
    // clean up avoiding multiple widget definitions 'hanging'
    _finish: function(inRowIndex) {
        this.inherited(arguments)
        dijit.byId('deleteme' + inRowIndex).destroy();
    },
    // needed to read the value properly, will work with either variant
    getValue: function(rowIndex) {
        var n = this.getEditNode(rowIndex);
        n = dijit.getEnclosingWidget(n);
        return n.get("value");
    }
});

最后一点,新布局

var layout = [[
      { name: 'Column 1', field: 'col1' },
      { name: 'Column 2', field: 'col2', 
        cellType: FilteringSelectCell, options: options, editable: true
      }
]];
