我正在使用带有复选框的Vuejs编写过滤器应用程序。当我使用单一复选框时它很好用。但是，当我检查超过2个复选框时，它会删除结果。
例如，当我选中绿色和红色时，它应显示标题1和标题2。 或者当我选中绿色，红色，活动，已完成时，它应显示标题1和标题2。

Vuejs代码：

,
checkedHealths: [],
checkedStatuses: []

computed: {
filteredProjects: function(){
let filterProjects = this.projects;

jQuery('input').iCheck({

jQuery('input').on('ifChecked', function(e){

答案 0 :(得分：3)
您的filterProjects方法看起来应该是这样的。
filteredProjects: function(){
let filterProjects = this.projects;
if (this.checkedHealths.length > 0){
filterProjects = filterProjects.filter(project => {
return this.checkedHealths.includes(project.Health);
})
}
if (this.checkedStatuses.length > 0){
filterProjects = filterProjects.filter(project => {
return this.checkedStatuses.includes(project.Status)
})
}
return filterProjects;
}
更新了fiddle。
基本上，您的旧过滤器代码是单独检查每个过滤器，您需要一次性处理它们。上面的代码遍历项目并检查项目的值是否在选定的过滤器值中。
你也在使用很多jQuery，你可以使用本机方法和Vue。
