有什么方法可以改变 slickgrid 表中特定行的背景颜色，同时保持其他行不变？？？我在用着

for ( var i = 0; i < grid.length; i++) {
    rowIndex[i] = {
        price : "editable-col",
        qty : "editable-col",
        ccy : "buy-row",
        side : "buy-col",
        symbol : "buy-row",
        enable : "buy-row"
    };
}
grid.setCellCssStyles("", rowIndex);

其中“editable-col”、“buy-row”和“buy-col”是包含背景/前景等颜色设置属性的 CSS 类。每当我想更改特定行的背景颜色时，我都必须更改整个网格的颜色（通过循环网格长度），或者如果我为特定行设置类，例如

rowIndex[5] = {
    price : "editable-col",
    qty : "editable-col",
    ccy : "buy-row",
    side : "buy-col",
    symbol : "buy-row",
    enable : "buy-row"
};
grid.setCellCssStyles("", rowIndex);

它为所需的行设置 css 类，但清除其他行的所有 css 属性，为避免这种情况，我也需要为其他行重置 css 类，我认为这在性能和时间方面不好，当你有成千上万的行。只是想知道有没有更好的方法来做到这一点而不触及其他行。?? 任何帮助将不胜感激。

假设您正在使用Slick.Data.DataView，您可以修改该getItemMetadata方法以将类动态添加到包含的行元素。然后，您可以简单地设置网格以根据行内的某些值更改行的样式。假设您的Slick.Data.DataView实例被称为dataView：

dataView.getItemMetadata = metadata(dataView.getItemMetadata);

function metadata(old_metadata) {
  return function(row) {
    var item = this.getItem(row);
    var meta = old_metadata(row) || {};

    if (item) {
      // Make sure the "cssClasses" property exists
      meta.cssClasses = meta.cssClasses || '';

      if (item.canBuy) {                    // If the row object has a truthy "canBuy" property
        meta.cssClasses += ' buy-row';      // add a class of "buy-row" to the row element.
      } // Note the leading ^ space.

      if (item.qty < 1) {                   // If the quantity (qty) for this item less than 1
        meta.cssClasses += ' out-of-stock'; // add a class of "out-of-stock" to the row element.
      }

   /* Here is just a random example that will add an HTML class to the row element
      that is the value of your row's "rowClass" property. Be careful with this as
      you may run into issues if the "rowClass" property isn't a string or isn't a
      valid class name. */
      if (item.rowClass) {
        var myClass = ' '+item.rowClass;
        meta.cssClasses += myClass;
      }
    }

    return meta;
  }
}

这将允许您将“购买行”类动态添加到行中。您可以将函数更改为对不同的类有多个条件，只要记住每一行的 CSS 类将基于行对象属性是有条件的。是这里ret.cssClasses的关键。它是在 HTML: 行中输出的字符串<div class="[ret.cssClasses]">。

您现在可以执行以下操作来更改行的类：

var row = dataView.getItem(5);

row.canBuy = true;
dataView.updateItem(row.id, row);
// The row element should now have a class of "buy-row" on it.

row.canBuy = false;
row.qty = 0;
dataView.updateItem(row.id, row);
// It should now have a class of "out-of-stock" and the "buy-row" class should be gone.

row.qty = 10;
row.rowClass = 'blue';
dataView.updateItem(row.id, row);
// It should now have a class of "blue" and the "out-of-stock" class should be gone.

是的，一种方法是简单地使用 jQuery：

var rowNumber = 3;
$($('.grid-canvas').children()[rowNumber]).css('background-color','red');

更新

要持久突出显示，您需要实现 getItemMetadata 函数。可以这样做：

html

<div style="width:600px;">
    <div id="myGrid" style="width:100%;height:500px;"></div>
</div>

css

.highlight{
    background-color: #ff0000 !important;
}

javascript

var grid;
var columns = [
    {id: "title", name: "Title", field: "title"},
    {id: "duration", name: "Duration", field: "duration"},
    {id: "%", name: "% Complete", field: "percentComplete"},
    {id: "start", name: "Start", field: "start"},
    {id: "finish", name: "Finish", field: "finish"},
    {id: "effort-driven", name: "Effort Driven", field: "effortDriven"}
];

var data = [];
for (var i = 0; i < 500; i++) {
    data[i] = {
        title: "Task " + i,
        duration: "5 days",
        percentComplete: Math.round(Math.random() * 100),
        start: "01/01/2009",
        finish: "01/05/2009",
        effortDriven: (i % 5 == 0)
    };
}
data.getItemMetadata = function (row) {

    if (this[row].title == 'Task 5'){
        return {
            cssClasses: 'highlight'

        };

    }
    return null;

}
grid = new Slick.Grid("#myGrid", data, columns, { enableColumnReorder: false });
