This tutorial outlines how you can work with the Select, Option, and Optgroup elements in HTML as well as in JavaScript. Data types for ALL HTML form elements is also discussed. Code from video: gist.github.co...
I have converted json into table using javascript ..so, I already have the table,th, & td elements..so how can i add dropdown filter to my table ? without adding all the elements staticly ..?
Adding filtering and sorting to your table means applying that to your data and redrawing the table. - custom sorting - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zVevl-K-m7Y.html - array filter method - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WrB_--bVbbs.html
You can also use Array.from() in this case, I find it a bit easier: Array.from(arrayLikeObject) let selected = Array.from(event.target.selectedOptions) let choices = selected.map(option => option.value) to even be more concise, you can send the map function as the second argument to Array.from() Array.from(arrayLikeObject, mapFunctionn) let choices = Array.from(event.target.selectedOptions, option => option.value)
I found this tutorial very helpful! Surprisingly, I never knew about "optgroup" in a select to group options! 😮 😊 Thank you so much for sharing such valuable information 🤑🤓💰💷
Group project will be successful thanks to your guidance. The only error I get is that "delectedOptions are not defined" . I have then in my HTML file under tag, I am using Visual Studio code editor. Is there any way to define it before I use it? Thank you in advance!
Man, you have some of the best web dev videos on youtube, but sometime I simply can't watch them because the volume is so low. And if I set my device volume high enough to understand you, whenever an ad or another video plays, it will torture my ears. I discovered you through some videos you uploaded about 3 years ago and I thought maybe you just started vlogging, you didn't have the equipment, editing skills, etc. But now.... I really think you should raise up the volume to the normal level, honestly I think this is one of the reasons you have so few subscribers, compared to other channels that don't even have 50% of the quality of the info you share... But the problem is the "presentation" (read this as poor/low recording sound level)
Thanks for your comments. This is the first complaint about volume that I have had on any of the videos that I have made since I switched to a new mic back in 2018. I know that there are older videos with volume issues but that was resolved with the new mic.
Need help to fill online form.i am using autofill extension for autofill. It does well for some field but it skips dropdown selection field and date of birth field. Is there any JS for that field???
Hello sir, you saved my day. I was stuck on getting the values of all selected options. After 3 days of cursing everything and everyone, I found out that I wrote "select.selectedOption" instead of "select.selectedOptions". 😐 Now everything works 😁 Thanks
I thought i'd have to look into this select element for quite a while before figuring how to properly use it in javascript. I came across your video and 10 minutes later my problem was solved. Thank you
Do you mean get the value of the selected option? That is just the value property of the select element. The select element also has a selectedIndex property that tells you the index number of the selected option. If the index is -1 then nothing is selected.
@@SteveGriffith-Prof3ssorSt3v3 hi, thank you for replying. But no, sorry I wasn't clear. I meant generating options dynamically, Let say you have two select elements in your HTML page and you want to show the options for the second select element based on the value of the first one, another scenario is if you want to generate the options based on data coming back from the server through an api request . Thank you 🙏
Hello! I'm looking for kind of select option but it's not a dropdown but a dot, a dot that when you click on that it fills inside with color I saw it was in every case black. Is that even a HTML syntax? I couldn't find that one, do you know maybe what it is?
@@SteveGriffith-Prof3ssorSt3v3 github.com/woocommerce/woocommerce-gutenberg-products-block/issues/1297 That's in a ''Cart Totals'' and then in a types of shipping, that's this dot-kind-of thing to select which shipping option you choose
