AngularJS提供了$http控件,該控件可作為從服務(wù)器讀取數(shù)據(jù)的服務(wù)。服務(wù)器進(jìn)行數(shù)據(jù)庫(kù)調(diào)用以獲取所需的記錄。AngularJS需要JSON格式的數(shù)據(jù)。數(shù)據(jù)準(zhǔn)備好后,可以使用$http通過(guò)以下方式從服務(wù)器獲取數(shù)據(jù)-
function studentController($scope,$https:) { var url = "data.txt"; $https:.get(url).success( function(response) { $scope.students = response; }); }
這里,檔案data.txt包含學(xué)生記錄。$http服務(wù)發(fā)出一個(gè)ajax調(diào)用并設(shè)置對(duì)其屬性students的響應(yīng)。學(xué)生模型可以用來(lái)繪制HTML表格。
[ { "Name" : "Sea Gull", "RollNo" : 101, "Percentage" : "80%" }, { "Name" : "Dinkar Kad", "RollNo" : 201, "Percentage" : "70%" }, { "Name" : "Robert", "RollNo" : 191, "Percentage" : "75%" }, { "Name" : "Julian Joe", "RollNo" : 111, "Percentage" : "77%" }]

要執(zhí)行此示例,您需要將testAngularJS.htm和data.txt文件部署到Web服務(wù)器。在網(wǎng)絡(luò)瀏覽器中使用服務(wù)器的URL打開文件testAngularJS.htm,然后查看結(jié)果。
