如何获取打印在console.log中的值，并将它们设置为输入字段中的值？

这里是的jsfiddle，包含所有我到目前为止 - https://jsfiddle.net/ubo1heru/

，通过该值被放入的console.log代码：

$("button").click(function() { 
    var dishkoMap = {}; 
    $("select[name='diskho'] > option:selected").each(function() { 
     var value = this.value; 
     if (dishkoMap[value]) { // if value already exists then increase it by 1 
     dishkoMap[value] += 1; 
     } else { 
     dishkoMap[value] = 1; 
     } 
    }); 
    // dishkoMap is a dictionary object so you won't see anything in alert. 
    // open the browser console and you can see the counts corresponding 
    // to each selected option 
    console.log(dishkoMap); 

    });

只需创建一个function其除了在印刷浏览器控制台更新您的input字段的值：

var printToDishkoMap = function (data) { 
    // Stringifying data is it is a JSON 
    $('input.diskhoval').val(JSON.stringify(data)); 
    console.log(data); 
} 

$("button").click(function() { 
    var dishkoMap = {}; 
    $("select[name='diskho'] > option:selected").each(function() { 
     var value = this.value; 
     if (dishkoMap[value]) { // if value already exists then increase it by 1 
     dishkoMap[value] += 1; 
     } else { 
     dishkoMap[value] = 1; 
     } 
    }); 
    // dishkoMap is a dictionary object so you won't see anything in alert. 
    // open the browser console and you can see the counts corresponding 
    // to each selected option 
    printToDishkoMap(dishkoMap); 
    });
