在另一个下拉列表中选择一个选项填充一个下拉列表 [英] Populate a dropdown on selecting an option from another dropdown Laravel

问题描述

希望您今天过得愉快，我很清楚地描述了我的问题:)

Hope you're having a nice day and i'm much clear to describe my problem :)

我有一个类别表和一个子类别表.在我看来，我想让用户选择一个属于某个类别的子类别，以添加一个产品(每个产品都属于一个子类别).为此，我想在用户选择类别时显示他的子类别.就像他从类别"中选择衣服"一样，我想显示诸如上衣，短裤等子类别.

I have a table of categories and a table of sub-categories. In my view, I want to let the user select a sub-category belonging to a category, for adding a product (Every product belongs to a sub-category). For that purpose, I want to show the user sub-categories when he selects a category. Like when he selects Clothes from Categories, I want to show Sub-categories like tops, shorts etc.

我该怎么做?只是一个主意就行.

How do I do that? Just an idea would work.

谢谢.

推荐答案

尝试一下

在第一个下拉列表onchange中调用getjson并将所选值传递给url，并在第二个下拉列表中加载结果.希望这对您有帮助

call getjson in first dropdown onchange and pass the selected value to url and load the results in second dropdown . Hope this helps you

$(document).ready(function(){
  $( "#firstdropdown" ).change(function() {
  var firstdropselectedvalue= $("#firstdropdown").val();   
  var url= test.php?selected=firstdropselectedvalue;
    $.getJSON(url, function(data){
  $.each(data, function(index, text) {
    $('#seconddropdown').append(
        $('<option></option>').val(index).html(text);
    );
  });
});

});

});
