Question

我想显示查询字符串（如果它不为空）作为输入字段的值，如<input name="campaign" type="hidden" value="ABC Campaign {% if (QueryString.GetValue("utm_source") != null) { return "| QueryString.GetValue("utm_source")"} %}" />

但由于所有的双引号而无法使其正常工作。我试过用反斜杠来逃避报价但是没有用。你能帮忙吗？（上面的代码放在表单＆gt;布局）

中

Answer 1

使用单引号括起整个语句并删除return语句的引号：

value='ABC Campaign {% if (QueryString.GetValue("utm_source") != null) { return  QueryString.GetValue("utm_source")} %}'

Answer 2

{％String.IsNullOrEmpty（查询字符串[＆＃34; utm_source＆＃34;]）查询字符串[＆＃34; utm_source＆＃34;]：＆＃34;＆＃34;％}

Answer 3

您还可以使用其他语法来获取查询参数：

{% !String.IsNullOrEmpty(QueryString.utm_source)?QueryString.utm_source:"" %}

Answer 4

更短！

 (function () {
    angular
        .module("idCardSupplierWarn", ['mm.foundation', 'security', 'message', "isteven-multi-select"])
        .controller('idCardSupplierWarnController', ['$translate', '$scope', 'serviceCockpit','idCardSupplierWarnService', function ($translate, $scope, serviceCockpit,idCardSupplierWarnService) {


            var urlSupplierWarningByRefDetail = 'rest/suppliers/warnings/supplier/details';

            var self = this;


             var params = {} ;

             params.idRefNum = idCardSupplierWarnService.getParamIdRefNum();
             params.idSupNum = idCardSupplierWarnService.getParamSupNum();
             params.codeSuppNum = idCardSupplierWarnService.getParamCodeSupNum();
                      console.log(params.codeSuppNum);


            serviceCockpit.loadData([urlSupplierWarningByRefDetail], params).then(function (results) {
                self.suppliersWarningsList = results[0].data;
            });


        }]);
})();

但如果你想让它有一个|在它之前，你必须使用

{％string.isnullorwhitespace（QueryString.utm_source）？＆＃34;＆＃34; ：＆＃34; |＆＃34; + QueryString.utm_source％}
