突出显示选定的 jsGrid 行

Question

我发现this example 在选中一行后会突出显示它，但问题是它会在选择另一行后突出显示前一行。

这是部分代码

//js
rowClick: function(args) {
        var $row = this.rowByItem(args.item);

      $row.toggleClass("highlight");
    }, 

//css
tr.highlight td.jsgrid-cell {
    background-color: green;
}

我找不到取消突出显示先前选择的行的解决方案

Answer 1

这个聚会有点晚了，但是@Narenda 接受的答案并没有完全解决我的问题。这可能会帮助以后偶然发现此问题的其他人。

如果您只需要一个选择，这里有一种方法：

扩展jsGrid插件，增加一个按索引找行的方法：

    jsGrid.Grid.prototype.rowByIndex = function(arg){
        //this._content.find("tr")[arg] returns a DOM element instead of a jQuery object
        //Pass the DOM element to the find method to get a jQuery object representing it
        return this._content.find(this._content.find("tr")[arg]);
    };

修改@Narenda回答中的rowClick函数：

    rowClick: function ( args ) {
        //Deselect all rows
        for(var i = 0; i<this.data.length; i++){
            this.rowByIndex(i).removeClass("jsgrid-highlight-row");
        }

        //Everything else as per the previous answer
        var $row = this.rowByItem(args.item),
        selectedRow = $("#jsGrid").find('table tr.jsgrid-highlight-row');

        if (selectedRow.length) {
            selectedRow.toggleClass('jsgrid-highlight-row');
        };
        $row.toggleClass("jsgrid-highlight-row");
        //Any other code to run on item click
    }

并添加一些 CSS。这模仿了默认主题中的行悬停：

    tr.jsgrid-highlight-row td.jsgrid-cell {
         background:#c4e2ff;
         border-color:#c4e2ff;
    }

您可以通过以下步骤来实现

1. 首先点击行，您需要像这样获得选定的行

   var selectedRow = $("#jsGrid").find('table tr.highlight').

2. 然后就可以使用了

   selectedRow.toggleClass('highlight') or selectedRow.removeClass('highlight')

演示

$("#jsGrid").jsGrid({
    width: "100%",
    height: "auto",
    paging: false,

    //for loadData method Need to set auto load true
    autoload: true,

    noDataContent: "Directory is empty",

    controller: {
        loadData: function(filter) {
            var data = [{
                nickname: "Test",
                email: "t@gmail.com"
            }, {
                nickname: "Test 1",
                email: "t1@gmail.com"
            }, {
                nickname: "Test 2",
                email: "t2@gmail.com"
            }, {
                nickname: "Test 3",
                email: "t3@gmail.com"
            }];
            return data;
        }
    },

    rowClick: function(args) {
        var $row = this.rowByItem(args.item),
            selectedRow = $("#jsGrid").find('table tr.highlight');

        if (selectedRow.length) {
            selectedRow.toggleClass('highlight');
        };
        
        $row.toggleClass("highlight");
    },

    fields: [{
        name: "nickname",
        type: "text",
        width: 80,
        title: "Name"
    }, {
        name: "email",
        type: "text",
        width: 100,
        title: "Email Address",
        readOnly: false
    }]
});

tr.highlight td.jsgrid-cell {
  background-color: green;
}

Se você veio em busca de uma solução na qual apenas 1 linha é selecionada e que também desseleciona a mesma linha, aqui está a solução：

如果您来寻找一个解决方案，其中只选择了 1 行并且还取消选择同一行，这里是解决方案：

selectedVal = null;

$(document).ready(function(){
jsGrid.Grid.prototype.rowByIndex = function(arg) {
         //this._content.find("tr")[arg] returns a DOM element instead of a jQuery object
         //Pass the DOM element to the find method to get a jQuery object representing it
         return this._content.find(this._content.find("tr")[arg]);
     };
});

rowClick: function (args) {

             selectedVal = args.item;

             let $row = this.rowByItem(args.item);

             if ($row.hasClass("highlight") === false) {
                 //Deseleciona todas as linhas
                 for (let i = 0; i < this.data.length; i++) {
                     this.rowByIndex(i).removeClass("highlight");
                 }
                 $row.toggleClass("highlight");

             } else {
                 selectedVal = null;
                 $row.toggleClass("highlight");

             }
             console.log(selectedVal);
         }
