由 微笑、不失礼 提交于 2020-04-16 02:10:00
问题 I have a question regarding a text input field, whose value is modified by a JavaScript function. Here is a simplified snippet of my code: <!doctype html> <html> <meta charset="utf-8"> <head> <title>Test Page</title> <script> function runScript() { document.getElementById("result").innerHTML = "Changing Text Input Value to Name 2"; document.getElementById("name_input0").value = "Name 2"; document.getElementById("name_hidden0").value = "Name 2"; } </script> </head> <body> <input type="hidden"

What is the efficient way to create a live search using javascript or jquery?

问题 I was making a live search for more than 10000 rows of the dataset. I have mentioned the available dom structure. Although I try to make a live search check every result after a single input, my browser is getting hang. Is there any other efficient way that I can reduce its complexity. <label class="label"> <input type="checkbox" name="123" value=""> </label> <label class="label"> <input type="checkbox" name="123" value=" General AUX"> General AUX </label> <label class="label"> <input type=

Advantages of script tag before closing body tag when using events [duplicate]

由 本秂侑毒 提交于 2020-04-11 04:47:52
问题 This question already has answers here : Where should I put <script> tags in HTML markup? (22 answers) Closed 5 years ago . These days it seems like people recommend placing the script tag just before the closing body tag as such.. <script src="//javascript.js"></script> </body> </html> If you are running the script immediately, this is a good thing because most of your DOM has mostly loaded. However, what if you are using the onload or DOMContentLoaded events to call your main script? In

Is there something better than document.execCommand?

由 自古美人都是妖i 提交于 2020-04-08 09:10:42
问题 When implementing a web-based rich-text editor, I read that document.execCommand is useful for performing operations on an HTML document (like making a selection bold). However, I need something a bit better. Specifically, I need to know exactly what text is added or removed from the innerHTML, and in what location (as an offset into the entire document's HTML representation). I considered using the built in document.execCommand along side DOM4's mutation observer, but execCommand doesn't

Vue中获取DOM元素 <div id="app"> <input type="button" value="获取元素" @click="getElement"> <h3 ref="myh3">今天天气真好啊</h3> </div> <script> var vm = new Vue({ el:'#app', data: { }, methods: { getElement(){ console.log(this.$refs.myh3.innerText) } }, }) </script> 还可以直接获取组件中的数据和方法，直接调用 <div id="app"> <input type="button" value="获取元素" @click="getElement" ref="button"> <h3 ref="myh3">今天天气真好啊</h3> <hr> <login ref="mylogin"></login> </div> <script> var login={ template:'<h1>登录组件</h1>', data(){ return { msg: 'son msg' } }, methods: { show(){ console.log("调用了子组件中的方法") } }, } var vm = new Vue({ el:'#app', data: { },

Asynchronous Promise blocking DOM

由 我的梦境 提交于 2020-04-07 08:57:08
问题 Asynchronous Promises aren't working as I expected in React (specifically React, but I think this will apply to other scenarios). They still seem to be blocking the main thread, essentially freezing my browser. I've got this method that handles a button click: onClick() { console.time('factorial') factorial(8000) // factorial is the culprit! .then(n => this.setState({ n })) console.endTime('factorial') } factorial returns a promise, and so, as expected, I get factorial: 2ms in the console.
