Ajax traverses jSon to modify and delete data
This time I will bring you Ajax traversal jSon to modify and delete data , what are the precautions for Ajax traversal jSon to modify and delete data, the following is a practical case, Let’s take a look.
No more nonsense, I will just post the code for you. The specific code is as follows:$.ajax({ url: "/business/findpersons.json", dataType: "json", type:"GET", success: function(doc) { var objs=eval(doc); for (var i = 0; i < objs.length; i++){ var personid=objs[i].personId; var name=objs[i].personName; var email=objs[i].personEmail; var sector=objs[i].personSector; var position=objs[i].personPosition; var password=objs[i].personPassword; $("#personList thead").append( "<tr>"+ "<th>"+name+"</th>"+ "<th>"+password+"</th>"+ "<th>"+email+"</th>"+ "<th>"+position+"</th>"+ "<th><input type='button' value='删除' name="+i+" class='deletePersonBut'></th>"+ "<th><input type='button' value='修改' name="+i+" class='updataPersonBut'></th>"+ "</tr>" ); var getA = "#personList .deletePersonBut[name="+ i + "]";//就这里获取的原因,那个i=objs.length的原因,感觉应该就是闭包的问题。 $(getA).click(function(){ var thid=$(this).parent(); var pid=thid.children(".deletePersonBut").attr('name'); alert(objs[pid].personId); }); var getA = "#personList .updataPersonBut[name="+ i + "]";//就这里获取的原因,那个i=objs.length的原因,感觉应该就是闭包的问题。 $(getA).click(function(){ var thid=$(this).parent(); var pid=thid.children(".updataPersonBut").attr('name'); alert(objs[pid].personId); }); } } });

Performance optimization methods for converting PHP arrays to JSON include: using JSON extensions and the json_encode() function; adding the JSON_UNESCAPED_UNICODE option to avoid character escaping; using buffers to improve loop encoding performance; caching JSON encoding results; and considering using a third-party JSON encoding library.

Annotations in the Jackson library control JSON serialization and deserialization: Serialization: @JsonIgnore: Ignore the property @JsonProperty: Specify the name @JsonGetter: Use the get method @JsonSetter: Use the set method Deserialization: @JsonIgnoreProperties: Ignore the property @ JsonProperty: Specify name @JsonCreator: Use constructor @JsonDeserialize: Custom logic

Using Ajax to obtain variables from PHP methods is a common scenario in web development. Through Ajax, the page can be dynamically obtained without refreshing the data. In this article, we will introduce how to use Ajax to get variables from PHP methods, and provide specific code examples. First, we need to write a PHP file to handle the Ajax request and return the required variables. Here is sample code for a simple PHP file getData.php:

In-depth understanding of PHP: Implementation method of converting JSONUnicode to Chinese During development, we often encounter situations where we need to process JSON data, and Unicode encoding in JSON will cause us some problems in some scenarios, especially when Unicode needs to be converted When encoding is converted to Chinese characters. In PHP, there are some methods that can help us achieve this conversion process. A common method will be introduced below and specific code examples will be provided. First, let us first understand the Un in JSON

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

PHP arrays can be converted to JSON strings through the json_encode() function (for example: $json=json_encode($array);), and conversely, the json_decode() function can be used to convert from JSON to arrays ($array=json_decode($json);) . Other tips include avoiding deep conversions, specifying custom options, and using third-party libraries.

In order to improve Ajax security, there are several methods: CSRF protection: generate a token and send it to the client, add it to the server side in the request for verification. XSS protection: Use htmlspecialchars() to filter input to prevent malicious script injection. Content-Security-Policy header: Restrict the loading of malicious resources and specify the sources from which scripts and style sheets are allowed to be loaded. Validate server-side input: Validate input received from Ajax requests to prevent attackers from exploiting input vulnerabilities. Use secure Ajax libraries: Take advantage of automatic CSRF protection modules provided by libraries such as jQuery.

Build an autocomplete suggestion engine using PHP and Ajax: Server-side script: handles Ajax requests and returns suggestions (autocomplete.php). Client script: Send Ajax request and display suggestions (autocomplete.js). Practical case: Include script in HTML page and specify search-input element identifier.
