Web Front-endJS TutorialWhat should I do if text cannot be copied or pasted by long pressing in the ionic app?What should I do if text cannot be copied or pasted by long pressing in the ionic app?
This time I will bring you what to do if the text in the ionic application cannot be copied and pasted by long pressing. What are the precautions to solve the problem that the text in the ionic application cannot be copied and pasted by long pressing. The following is a practical case. Let’s take a look.
The project is about to go online, but it encountered a strange problem. The text in ionic cannot be copied and pasted like a normal wap page.
I looked through official documents and Chinese websites, but there is no explanation on this issue.
The following URL is the first result of Google search:
http://ionichina.com/topic/55d18fff628dd6dc21b07d75
I have tried all the methods here, but they are not ideal.
Later, after searching for information from various sources, this problem was solved. Share it with everyone next.
Go directly to the code:
html part
<html ng-app="ionicApp"><head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
<title>Ionic文字复制问题</title>
<link href="http://code.ionicframework.com/1.0.0-beta.4/css/ionic.css" rel="stylesheet">
<script src="http://code.ionicframework.com/1.0.0-beta.4/js/ionic.bundle.js"></script></head><body ng-controller="MyCtrl">
<ion-header-bar class="bar-positive">
<h1 id="ionic-nbsp-测试copy">ionic 测试copy</h1>
</ion-header-bar>
<ion-content overflow-scroll='true'>
<div class="selectable">幻灯片1测试文字，试试可以复制</div>
</ion-content></body></html>css part
ion-content{ overflow-scroll: true;
}.scroll-content { -webkit-user-select: auto !important; -moz-user-select: auto !important; -ms-user-select: auto !important; user-select: auto !important;
}.selectable { -webkit-user-select: auto;//控制网页内容选择范围
}js part
angular.module('ionicApp', ['ionic'])
.controller('MyCtrl', function($scope) {
stop_browser_behavior: false self.touchStart = function(e) {
self.startCoordinates = getPointerCoordinates(e); if ( ionic.tap.ignoreScrollStart(e) ) { return;
} if( ionic.tap.containsOrIsTextInput(e.target) ) { // do not start if the target is a text input
// if there is a touchmove on this input, then we can start the scroll
self.hasStarted = false; return;
}
self.isSelectable = true;
self.enableScrollY = true;
self.hasStarted = true;
self.doTouchStart(e.touches, e.timeStamp); // e.preventDefault();};
});We can see through the code, First, add overflow-scroll='true' in the html, and then add a custom class on the container where we want to copy the text. In the code, we add '.selectable' and set our css style on this class. .
It should be noted here that this custom class cannot be added to the specific tag of ionic. As follows:
<ion-content class="selectable" overflow-scroll="true">
It is invalid to write it like this. We must write it like this:
<ion-content overflow-scroll='true'>
<div class="selectable">幻灯片1测试文字，试试可以复制</div> </ion-content>means that I didn’t write it correctly because of this. Debugging After a long time, I can’t get the effect. . . .
The last step is to copy the above js code in the controller corresponding to the page.
I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.
Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AMThe shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AMJavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript: Exploring the Versatility of a Web LanguageApr 11, 2025 am 12:01 AMJavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.
