单元格编辑后的SlickGrid样式 [英] SlickGrid styling after cell edit

问题描述

我正在将SlickGrid（2.0）dataView与slick.editors结合使用。在网格中，用户可以编辑任意数量的单元格，然后修改基础网格数据，以便在网格滚动时保留编辑内容。这很好。但我也想为所有编辑提供视觉反馈，因为只有在用户单击保存编辑按钮之前，这些编辑才会保存到数据库中。

I'm using SlickGrid (2.0) dataView with slick.editors. In the Grid, a user can edit any number of cells which then modifies the underlying grid data so that the edits are maintained when the grid scrolls. This works great. But I also want to provide visual feedback for all the edits since these are not saved to the database until user hit "Save Edits" button.

问题是编辑器方法在读回更改的网格数据后会重置单元格。我需要保持背景颜色的更改以表明它已被编辑。有人能做到这一点吗？

Problem is that the editor method resets the cell after it reads back the changed grid data. I need to maintain a background color change to indicate that it's been edited. Has anyone been able to do this?

以下是相关代码（简单的整数编辑器）：

Here is the relevent code (simple Integer editor):

function IntegerCellEditor(args) {
    var $input;
    var defaultValue;
    var scope = this;
    this.init = function() {
        $input = $("<input type=text class='edited' type=text style='font:normal 12px arial; width:95px; text-align:right; border:none;' />");
        $input.bind("keydown.nav", function(e) {
            if (e.keyCode === $.ui.keyCode.LEFT || e.keyCode === $.ui.keyCode.RIGHT) {
                e.stopImmediatePropagation();
            }
        });
    $('#saveChanges').removeAttr("disabled");   // remove disabled attribute from "Save Changes" btn
        $input.appendTo(args.container);
        $input.focus().select();
    };
    this.destroy = function() {
        $input.remove();
    };
    this.focus = function() {
        $input.focus();
    };
    this.loadValue = function(item) {
        defaultValue = item[args.column.field];
        $input.val(defaultValue);
        $input[0].defaultValue = defaultValue;
        $input.select();
    };
    this.serializeValue = function() {
        return parseInt($input.val(),10) || 0;
    };
    this.applyValue = function(item,state) {
        item[args.column.field] = state;
    };
    this.isValueChanged = function() {
        return (!($input.val() == "" && defaultValue == null)) && ($input.val() != defaultValue);
document.getElementsByClassName('ui-widget-content slick-row')[row].className += 'edited';
        };
        this.validate = function() {
            if (isNaN($input.val()))
                return {
                   valid: false,
                   msg: "Please enter a valid integer"
               };
            return {
                valid: true,
                msg: null
           };
        };
        this.init();
    }

此行无济于事，我不知道该怎么做：

This line does nothing and I can't figure out how to do this:

document.getElementsByClassName('ui-widget-content slick-row')[row].className += 'edited';

谢谢

推荐答案

我不是SlickGrid方面的专家，但请看一下示例14 ，我认为它具有类似的信息可以为您提供帮助。

I am not an expert in SlickGrid but take a look a Example 14, I think it has similar information that would help you.

我的想法是：

• 订阅grid.onCellChange事件


• 存储对象更改


• 使用grid.setCellCssStyles（'highlight' ，更改）以更新CSS或grid.addCellCssStyles

希望至少能有所帮助。
