是什么啊 我是新手 真的不懂那么多 还有 你写的那段代码是不是少个 ) 啊?


<script>function foo() {  var res = [];  var texts = document.getElementsByName("p");  for(var i in texts) res.push(texts[i].value;}</script>

res 中就是


<script> <br /><script> <br />function foo() { <br /> var res = ["push":"url"]; <br /> var texts = document.getElementsByName("p"); <br /> for(var i in texts) res.push(texts[i].value;) <br />} <br /></script>请问您是不是这个意思啊

function foo() {
  var res = []; //定义一个数组,用于存放各文本框的值
  var texts = document.getElementsByName("p"); //获取全部名字为 p 的文本框
  for(var i in texts) res.push(texts[i].value ); //读取每个文本框的值到数组
}

做大事者不拘小节

res就是定义了一个数组。

function foo() {
  var res = []; //定义一个数组,用于存放各文本框的值
  var texts = document.getElementsByName("p"); //获取全部名字为 p 的文本框
  for(var i in texts) res.push(texts[i].value ); //读取每个文本框的值到数组
}

做大事者不拘小节


<script> <br />function foo() { <br /> var res = []; <br /> var texts = document.getElementsByName("p"); <br /> for(var i in texts) res.push(texts[i].value;) <br /> alert(url='city.php?module=city&p='+paixu); <br /> location.href=url; <br />} <br /></script>我这样是不是可以带着获取到的p的值 去city页面啊  怎么保存呢

res 是结果数组,传送时需转换成字符串(因为php不认得js数组):res = res.join(',')
然后放到目标 url 中

我不是很懂这个意思  换一种方法用post提交
<script> <br />function foo() { <br /> var res = []; <br /> var texts = document.getElementsByName("p"); <br /> for(var i in texts) res.push(texts[i].value;) <br /> $.post("server.php", {"res = res.join(',')"}, function(data){ <br /> alert(data); <br /> <br /> }; <br /></script>
这样获取res的数组么?  怎么感觉怪怪的

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

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.
