![]() ![]() Responsible for the development of JavaScript are Mozilla Fundation (which is successor of Netscape Navigator) and Ecma International. Try it live by yourself: Live demo (Open this link in this tab only since it will create a previous page ) Feel free to reach me out via Twitter codewithsnowbit. It will only work if the previous page exists. In the following years, the development of JavaScript was continued and in cycles were released new versions of specification. The history.back () method loads the previous URL from the history list. Other browser vendors could use this specification to prepare their implementation. In 1997 was published the language specification called ECMAScript as a ECMA-262 standard. Netscape submitted JavaScript to Ecma International to “standardize the syntax and semantics of a general purpose, cross-platform, vendor-neutral scripting language”. Whenever users come back to the page which is added to history through then an event with the name will be triggered by the browser in that event object with Open a new tab go to a webpage, say. Industry needs caused that decided to standardize language. Since that time there were two versions of JavaScript. In 1996 they released Internet Explorer 3 with their own implementation of JavaScript called JScript. In this time Microsoft to compete with Netscape decided to include scripting technologies in their browser. Soon JavaScript 1.1 was released in Netscape Navigator 3. JavaScript 1.0 was a success and helped Netscape Navigator’s to hold the leader position of the market. ![]() This, but above all the desire to use the growing popularity of Java to call positive associations with a new language where reasons that it was finally called JavaScript. Also implementation of the language for server-side was introduced. LiveScript followed a lot of Java features. In the same 1995 year new developed scripting language was renamed to JavaScript and used in next beta version of Netscape Navigator 2. First version of new language had Mocha name, whereas official version used in Netscape Navigator 2 beta version was called LiveScript. In 1995 Netscape Communications employed Brendan Eich to develop scripting language for web browser. Eventually they decided to create scripting language that would complement Java and has a similar syntax. Then they wanted adopting and embedding a existing programming language like Scheme, Perl or Python. First Netscape Communications cooperate with Sun Microsystems to use in Netscape Navigator Sun’s programming language Java. Here's the same code as above, using history.go(-1) instead of history.back().JavaScript language comes from the times when early web browsers were being developed. Netscape Communications company in 1994 created Netscape Navigator that became the most popular web browser in the 90s.Ĭompany’s board quickly realized that browsers should allow create more dynamic websites and do some activities that do server-side languages, like input validation. If you specify the number -1 as your argument, the browser goes back one page in the browser's history. With computer programming, this is called an argument. ![]() You can specify which history item by putting a number inside the parentheses. The history.go() method tells the browser to go to a specific page in the user's browsing history. ![]() If you click it, you go back to the previous page in your history. Insert the following HTML into your web page: Here, we create the button using a element, containing an element of the button type. One way to use this JavaScript is to add it to the onclick event attribute of a button. You can use the history.back() method to tell the browser to go back to the user's previous page. In a web browser, the built-in JavaScript object window has an object called history containing the URLs a user has visited in their current browser window. If there isn’t, we fall back to using history.back () as. For example, if the user opens your page in a new browser tab or window, nothing happens when they click the button. Here’s a way you can do it: // On button press, or something else: document.referrer window.location document.referrer : history.back() This looks to see if we have a referrer, which is the last page that the user came from before this page. This might, or might not be a problem for you. These buttons don't work if the user has no browsing history. You could use a button add an onclick event listener and then use the history API to go back to the previous page: But that’s pretty obtrusive, it won’t work if JavaScript is disabled, and the button still sits there doing nothing.![]()
