InnerHTML and innerText Usages

 innerHTML is use to declare some element's inner HTML and innerText

The folowing playgronund shows the difference. Try type in some html code,such as h1, h2, or button tags to see effects.

innerHTML example

hi

innerText example

<h2>hi</h2>

Plauground Source Code

<textarea oninput="showhtml.innerHTML = this.value;showtext.innerText = this.value;"><h2>hi</h2></textarea>
<h3>innerHTML example</h3>
<div id="showhtml"><h2>hi</h2></div>
<h3>innerText example</h3>
<div id="showtext">&lt;h2&gt;hi&lt;/h2&gt;</div>
The idea is when you want to output html tags as the wording in the browser, use innerText. If you want to output the html elements, use innerHTML

The other thing is innerHTML and innerText show opposite results have you grab what is inside the tags. What I mean is when you want to output html in text, you use innerText, but when you want to grab the DOM elements' html in text, you use innerHTML.

Consider the folowing code to see why:
<div id = "example">
    <h3>inside text</h3>
</div>
<div id = "showexampletext"></div>
<div id = "showexamplehtml"></div>
<div id = "showexamplehtmlintext">
</div>
<script>
    showexampletext.innerHTML = example.innerText; 
    showexamplehtml.innerHTML = example.innerHTML; 
    showexamplehtmlintext.innerText = example.innerHTML;
</script>

Results:

Below is what is in <div id = "example"></div>, which is <h2>inside text</h2>

inside text

showexampletext:
showexamplehtml:
showexamplehtmlintext:

If you are lasy typing using &lt; for < and &gt; for > when editing html, you can also use the innerText to outpot it in the DOM.

How to Make A Reusable Image Slideshow HTML Component With Vanilla JavaScript

Image
The image slide show I am making has no animation. The mechanism for displaying different slide is by using the display CSS property. The image with display none will not show, while the one with display block will. I will start build one that relys on HTML code then I will build one that relys on JavaScipt that renders the slide show onto the webpage. HTML Slideshow Setup A HTML image slide show can follow the following logic: An image is shown and the others are hidden, by defining the CSS display property to "block" to show and "none" to hide. An index is used to control the CSS display property of each slide with the initial index of 1. On initiation, all image tags for the slide show will be given the CSS property correspoding to whether it's shown or not. A left arrow and a right arrow are used to control the index with onclick event handlers. In order to position the left and right control...

HTML Tags and Inline CSS that Work In Plotly.js Title

When we create a plot object with Plotly.js, we throw in 3 basic parameters in the Plotly object which are the plot container id, data and layout, like this one: Plotly.newPlot('myDiv', data, layout); And in the layont object, there is a property, called title. The title property can be defined with an string, which will simply be just the title text that is going to display on the top of the plot.  I want to style my chart title when I use Plotly.js.; var layout = { title:`Plot Title` } Or in the text object within the title property. var layout = { title:{text:`Plot Title`} } Plot;y'js has some built-in title properties which we can use to style the title, sush as font color, family, size, padding, and position with x or y. var layout = { title: { text:'Plot Title', font: { family: 'Courier New, monospace', size: 24 }, xref: 'paper', x: 0.05, } }; Problems But I want to add a HTML tag...

How to Type Spaces In HTML Input And Display In the Browser

Image
When we type a space in an input and use it in JavaScript. The space will be recorded as text just like regular texts. Type In Multiple Spaces When we type some text with many spaces and displays the text in the browser, muiltple spaces will be parsed into one space, if they are connected. Type some text with spaces here: <input oninput="show_1.innerHTML = this.value" /><br /> <div id="show_1"></div> What does JavaScript Do to the Spaces? JavaScript does nothing to the spaces. It preservs all the spaces we type. The following code converts spaces into the letter "a". Space is represnted by \x20 in JavaScript. Type some text with spaces here: <input oninput="show_2.innerHTML = this.value.replace(/\x20/g,'a');" /><br /> <div id="show_2"></div> Why doesn't the Spaces Show in the Browser? Because the connected spaces are parsed into one space in HTML. ...
