我正在开发一个使用 Angular 围绕 Node.js api 服务器创建 SPA 的业务应用程序。我决定使用状态机的 ui-router 原因及其嵌入 url 的直观方式,但是在指令中创建动态 URL 时我偶然遇到了一个小挑战。
我将 jQuery Datatables 用于我的数据网格作为指令,但使用“fnRender”生成的任何操作链接似乎都不会将“ui-sref”编译为它们各自的“href”链接。指令代码如下:
app.directive('datatable', function ($http) {
return {
restrict: 'A',
link: function ($scope, $elem, attrs) {
var responsiveHelper;
var breakpointDefinition = {
tablet: 1024,
phone : 480
};
var options = {
bDeferRender: true,
sPaginationType: "full_numbers",
oLanguage: {
sEmptyTable: "No records returned",
sSearch: "<span>Search:</span> ",
sInfo: "Showing <span>_START_</span> to <span>_END_</span> of <span>_TOTAL_</span> entries",
sLengthMenu: "_MENU_ <span>entries per page</span>",
sProcessing: "Loading..."
},
sDom: "lfrtip",
oColVis: {
buttonText: "Change columns <i class='icon-angle-down'></i>"
},
oTableTools: {
sSwfPath: "js/plugins/datatable/swf/copy_csv_xls_pdf.swf"
},
bAutoWidth : false,
fnPreDrawCallback: function () {
if (!responsiveHelper) {
responsiveHelper = new ResponsiveDatatablesHelper($elem, breakpointDefinition);
}
},
fnRowCallback : function (nRow, aData, iDisplayIndex, iDisplayIndexFull) {
responsiveHelper.createExpandIcon(nRow);
},
fnDrawCallback : function (oSettings) {
responsiveHelper.respond();
}
};
if (typeof $scope.dtOptions !== 'undefined') {
angular.extend(options, $scope.dtOptions);
}
if (attrs['dtoptions'] === undefined) {
for (property in attrs) {
switch (property) {
case 'sajaxsource':
options['sAjaxSource'] = attrs[property];
break;
case 'sajaxdataprop':
options['sAjaxDataProp'] = attrs[property];
break;
}
}
} else {
angular.extend(options, $scope[attrs['dtoptions']]);
}
if (typeof options['sAjaxSource'] === 'undefined') {
throw "Ajax Source not defined! Use sajaxsource='/api/v1/*'";
}
if (typeof options['fnServerData'] === 'undefined') {
options['fnServerData'] = function (sSource, aoData, resultCb) {
$http.get(sSource, aoData).then(function (result) {
resultCb(result.data);
});
};
}
options.aoColumnDefs = [];
$elem.find('thead th').each(function() {
var colattr = angular.element(this).data();
if (colattr.mdata) {
if (colattr.mdata.indexOf("()") > 1) {
var fn = $scope[colattr.mdata.substring(0, colattr.mdata.length - 2)];
if (typeof fn === 'function') {
options.aoColumnDefs.push({
mData: fn,
sClass: colattr.sclass,
aTargets: [colattr.atargets]
});
} else {
throw "mData function does not exist in $scope.";
}
} else {
options.aoColumnDefs.push({
mData: colattr.mdata,
sClass: colattr.sclass,
bVisible: colattr.bvisible,
aTargets: [colattr.atargets]
});
}
} else {
if (colattr.fnrender.indexOf("()") > 1) {
var fn = $scope[colattr.fnrender.substring(0, colattr.fnrender.length - 2)];
if (typeof fn === 'function') {
options.aoColumnDefs.push({
fnRender: fn,
sClass: colattr.sclass,
aTargets: [colattr.atargets]
});
} else {
throw "fnRender function does not exist in $scope.";
}
} else {
options.aoColumnDefs.push({
fnRender: function (oObj) {
return "<a tooltip class='btn' title='View' ui-sref=\""+colattr.tag+".show({slug:\'"+oObj.aData._id+"\'})\"><center class=\"icon-search\"></center></a>";
},
sClass: colattr.sclass,
bVisible: colattr.bvisible,
aTargets: [colattr.atargets]
});
}
}
});
$elem.dataTable(options);
$(".dataTables_length select").wrap("<div class='input-mini'></div>").chosen({disable_search_threshold: 9999999 });
}
}
});
它运行起来没有复杂性,甚至生成以下锚标记:
<a ui-sref="organisation.show({slug:'527a44c02aa9ce3a1c3fbc17'})"></a>
但是,ui-router 不会将其编译为相应的状态 url。可能是什么问题?是否有一些我可能错过的配置?
谢谢
