Question

var selectColumns = new Array();
selectColumns[0] = { TableName: "DeploymentRosterView", ColumnName: "ArrivedOn" };
selectColumns[1] = { TableName: "DeploymentRosterView", ColumnName: "DepartedOn" };
selectColumns[2] = { TableName: "DeploymentRosterView", ColumnName: "RoleType" };
selectColumns[3] = { TableName: "DeploymentRosterView", ColumnName: "AdjusterFirstName" };
selectColumns[4] = { TableName: "DeploymentRosterView", ColumnName: "AdjusterLastName" };

上面的工作是用JavaScript创建我的数组，但有没有更优雅的方式来编写上述内容？像对象初始化器一样？只是想知道

Answer 1

您可以内联创建：

var selectColumns = [
    { TableName: "DeploymentRosterView", ColumnName: "ArrivedOn" },
    { TableName: "DeploymentRosterView", ColumnName: "DepartedOn" },
    { TableName: "DeploymentRosterView", ColumnName: "RoleType" },
    { TableName: "DeploymentRosterView", ColumnName: "AdjusterFirstName" },
    { TableName: "DeploymentRosterView", ColumnName: "AdjusterLastName" }];

Answer 2

你可以创建一个像：

这样的数组

var selectColumns = [
    { TableName: "DeploymentRosterView", ColumnName: "ArrivedOn" },
    { TableName: "DeploymentRosterView", ColumnName: "DepartedOn" },
    { TableName: "DeploymentRosterView", ColumnName: "RoleType" },
    { TableName: "DeploymentRosterView", ColumnName: "AdjusterFirstName" },
    { TableName: "DeploymentRosterView", ColumnName: "AdjusterLastName" }
];

Answer 3

你可以这样重组：

var selectColumns = {

  "DeploymentRosterView": {
    "ColumnNames": ["DepartedOn", "RoleType", "AdjusterFirstName", "AdjusterLastName"]
  }
};

// Loop through all views
for (view in selectColumns)
{
  var v = selectColumns[view].ColumnNames;
  alert('Column names for "' + view + '" is: ' + v.join(', '));
}
