动态添加INPUT,获取值的问题
<script> <br /> function add() { <br /> // 创建table 行标签tr <br /> var trObj = document.createElement("tr"); <br /> // 设置行内容 <br /> trObj.innerHTML = "<td width='150px'><input name='firstName'/><td width='150px'>" <br /> + "<input name='lastName'/><td width='130px'><input type='button' value='Add' onclick='add()'> " <br /> + "<input type='button' value='Del' onclick='del(this)'>"; <br /> // 将行内容添加到表格中 <br /> document.getElementById("tb").appendChild(trObj); <br /> } <br /> <br /> function del(obj) { <br /> // 直接删除当前对象的父节点的父节点 <br /> document.getElementById("tb").removeChild(obj.parentNode.parentNode); <br /> } <br /> <br /> function compareTRs(oTR1, oTR2) { <br /> // 获取行中的需要比较的firstName列的值 <br /> var sValue1 = oTR1.firstElementChild.firstElementChild.value; <br /> var sValue2 = oTR2.firstElementChild.firstElementChild.value; <br /> // 进行比较 <br /> return sValue1.localeCompare(sValue2); <br /> } <br /> <br /> function sortTable(){ <br /> // 获取表格 <br /> var oTable = document.getElementById("tb1"); <br /> // 获取表格中tBody主体域 <br /> var oTBody = oTable.tBodies[0]; <br /> // 获取oTBody域中行集合 <br /> var colDataRows = oTBody.rows; <br /> // 新建行数组,用于存放行内容 <br /> var aTRs = new Array; <br /> <br /> // 将oTBody中的行内容添加到aTRs中 <br /> for (var i=0; i < colDataRows.length; i++) { <br /> aTRs[i] = colDataRows[i]; <br /> } <br /> <br /> // 若oTable的sortCol 属性为空,对数组进行反转,否则进行排序 <br /> if (oTable.sortCol) { <br /> aTRs.reverse(); <br /> } else { <br /> aTRs.sort(compareTRs); <br /> } <br /> <br /> // 创建代码片段,存放排序后的行数据 <br /> var oFragment = document.createDocumentFragment(); <br /> for (var i=0; i < aTRs.length; i++) { <br /> oFragment.appendChild(aTRs[i]); <br /> } <br /> <br /> // 将存放有排序后行数据的代码片段添加到表格主体oTBody上 <br /> oTBody.appendChild(oFragment); <br /> <br /> // 设置排序标识 <br /> oTable.sortCol = true; <br /> } <br /> </script>
php.php如何得到a b c d e f 的值。
得到值后,然后变成下
a键名,b是值
c键名,d是值
e键名,f是值
搞成一个二维数码,存入数据库
这个主要是做产品属性增加的。
回复讨论(解决方案)
有 name 属性就可获得
同名时应用数组形式命名

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
