如何在不刷新的情况下将数据插入字段？ [英] How to insert data into field without refresh?

问题描述

我需要知道如何在不刷新字段的情况下从数据库添加数据？我的意思就像电子邮件中添加联系人的工作一样。如果我点击添加按钮，我需要打开一个小窗口和其中的联系人。如果我检查一个或两个联系人，然后按插入，它应该被插入'收件人'字段，而不刷新父页.. !!

I need to know how can I add data from the database without refreshing the field ? I mean just like the working of Add Contacts in the Email. If I click the 'Add' button, I need to open a small window and contacts within it. If I check one or two contacts and press insert, it should be inserted in the 'To' field without refreshing the parent page..!!

我该怎么做在PHP或JavaScript？请帮助我：）

推荐答案

您需要使用ajax来执行此操作。 Ajaxform是一个很好的插件，用于动态地向表单中的页面添加数据。你也可以使用jquery中的$ .ajax。 http://jquery.malsup.com/form/#ajaxForm

You'll need to use ajax to do so. Ajaxform is great plugin for dynamically adding data to a page from a form. You can use $.ajax from jquery as well. http://jquery.malsup.com/form/#ajaxForm

$(document).ready(function() { 
    var options = { 
        target:        '#output1',   // target element(s) to be updated with server response 
        beforeSubmit:  showRequest,  // pre-submit callback 
        success:       showResponse  // post-submit callback 

        // other available options: 
        //url:       url         // override for form's 'action' attribute 
        //type:      type        // 'get' or 'post', override for form's 'method' attribute 
        //dataType:  null        // 'xml', 'script', or 'json' (expected server response type) 
        //clearForm: true        // clear all form fields after successful submit 
        //resetForm: true        // reset the form after successful submit 

        // $.ajax options can be used here too, for example: 
        //timeout:   3000 
    }; 

    // bind form using 'ajaxForm' 
    $('#myForm1').ajaxForm(options); 
}); 

或常规ajax

$.ajax({
  url : url,
  data : {name : name}
  dataType : 'json',
  success : function(data) {}
});
