Dynamic routing parameters, multiple implementations of components receiving passed data ($route.params, props, props are set as objects)
1. Obtain path parameters through $route.params <h2> Received the value you passed: {<!– –>{$route.params.username}} — {<!– –>{$route.params.post_id} }</h2> mounted(){ // Read data from the routing information object $route — this should be included when writing in the script console.log(this.$route.params); this.pid = this.$route.params.post_id; this.uname = this.$route.params.username; } 2. Receive parameters through props Note: props is used […]

AJAX principle (XMLHttpRequest+Promise+URLSearchParams)
1. XMLHttpRequest The XMLHttpRequest (XHR) object is used to interact with the server. Through XMLHttpRequest, a specific URL can be requested to obtain data without refreshing the page. This allows the web page to update partial content of the page without affecting the user’s operation. XMLHttpRequest is heavily used in AJAX programming. Relationship: Axios internally […]

If it is isolated by data, ${params.dataScope} is replaced and optimized for sql replacement
If it is isolated by data, ${params.dataScope} is replaced and optimized for sql replacement Security issue: Risky SQL query: MyBatis solution If the frame-based data isolation is achieved through ${params.dataScope} However, during the code security scan, the $ symbol will prompt a risky SQL query: MyBatis So we need to optimize here refer to: MyBatis-Plus […]
[Solved] Routing uses params to pass boolean value logic disorder, solution
Article table of contents question wrong reason Solutions Solution (different types passed in params and query) Questions Use routing to carry parameters and use params to transmit, page one is passed to page two, page two can receive “false”, but page two has always been logically wrong Reason for error The params pass is a […]
[Solved] Some problems with passing parameters of meta and params in routing (can be passed but not passed, empty, collocation, click to pass multiple parameters to report an error)
When a routing object does not need to display a component, it can be set through meta Login registration does not require Footer, which is solved by routing meta configuration The path judgment can be obtained from the route, which can be solved but troublesome It is done by configuring the meta settings in the […]
