Introduction to JavaScript Counter

Web development, programming languages, Software testing & others

Syntax and Parameters

In Javascript, the counter is one of the features for the UI interactions. It will be implemented in one or more ways like we have to initialize and declaring the count variables, and another way is we have to use Pusher API for counting the user-defined customized views on the web page.

var v= 60; var v1 =setInterval(functionname,1000);

-Using the above codes, we will call some default methods for binding the datas without encryption. For each channel, the vote count will vary depending on the initialized voter variable in the script.

Apart from that, javascript has some default plugins like scroll-triggered Counter Plugin, which comes under the chúng tôi because it’s based upon the user requirement for counting the datas in the UI. It also stores in the browser cache for temporary storage. We need to make two functions in the javascript. It takes the value of a text area element to calculate the total words, which will be displayed on the placeholder element.

Examples of JavaScript Counter

Following are the examples.

Example #1

Code:

function demo() { var d = document.getElementById (“first”); if (window.getComputedStyle) { var comp = window.getComputedStyle (d, null); try { var v = comp.getPropertyCSSValue (“content”); try { varcvalue = null; if (v) { if (v.cssValueType == CSSValue.CSS_PRIMITIVE_VALUE) { if (v.primitiveType == CSSPrimitiveValue.CSS_COUNTER) { cvalue = value.getCounterValue (); } } else { if (v.cssValueType == CSSValue.CSS_VALUE_LIST) { if (v[0].primitiveType == CSSPrimitiveValue.CSS_COUNTER) { counterValue = v[0].getCounterValue (); } } } } } if (cvalue) { alert (“(identifier: ” + cvalue.identifier + “, listStyle: ” + cvalue.listStyle + “, separator: ” + cvalue.separator + “)”); } else { alert (“The value of the counter-increment property is not a counter function!”); } } catch (e) { alert (“Please find the error your browser does not support the getCounterValue method!”); } } catch (e) { alert (“Please find the error your browser does not support the getPropertyCSSValue method!”); } } else { alert (“Please find the error your browser does not support the getComputedStyle method!”); } }

Example #2

Code:

p { display: inline; font-size: 40px; margin-top: 0px; } var c = new Date(“Jul 28, 2023 22:24:16”).getTime(); var mf = setInterval(function() { var n = new Date().getTime(); var t = c – n; var da = Math.floor(t / (1000 * 60 * 60 * 24)); var ho = Math.floor((t % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)); var mins = Math.floor((t % (1000 * 60 * 60)) / (1000 * 60)); var sec = Math.floor((t % (1000 * 60)) / 1000); document.getElementById(“days”).innerHTML = da + “d “ document.getElementById(“hours”).innerHTML = ho + “h “ document.getElementById(“mins”).innerHTML = mins + “m “ document.getElementById(“secs”).innerHTML = sec + “s “ if (t < 0) { clearInterval(mf); document.getElementById(“days”).innerHTML = “” document.getElementById(“hours”).innerHTML = “” document.getElementById(“mins”).innerHTML = “” document.getElementById(“secs”).innerHTML = “” document.getElementById(“end”).innerHTML = “TIMES UP Please try new dates!!”; } }, 1000);

Output:

Example #3

Code:

var tf = 60; var e = document.getElementById(‘first’); var t = setInterval(demo, 1000); function demo() { if (tf == -1) { clearTimeout(t); second(); } else { e.innerHTML = tf + ‘ Time seconds for remaining’; tf–; } } function second() { alert(“Hi Welcome User”); }

Output:

Conclusion

Generally, JS is used for snippet actions. It will be available for all the scenarios. It increments the counter values automatically based on requirements given by the user. If we need to change the customized times, it will do the changes only in the scripts, even though we are not in touch with html codes.
