I am working with two textboxes
<input id='random_value' name='random_name' value='First'
<input id='random_value' name='random_name' value=''
My challenge is to replace the value of a textbox that currently has 'First' with 'Second', without using either the textbox id or name. Do you think this is achievable?
This custom function is specifically designed to update the content within all input elements from "First" to "Second":
function replaceTextContent() {
var elements = document.getElementsByTagName("INPUT");
for(var index = 0, limit = elements.length; index < limit; index++) {
if(elements[index].value == "First")
elements[index].value = "Second";
}
}
Here is a way to make selections:
var input = document.getElementsByTagName("INPUT");
var j = 0;
for (var i = 0; i < input.length; i++) {
if (input[i].type == "text") {
if (input[i].value == "First") {
input[i].value == "Second"
}
}
}
If you know the index of the element in the DOM, you can do this directly:
<HTML>
<FORM>
<input id='random_value' name='random_name' value='First'/>
<input id='random_value' name='random_name' value=''/>
</FORM>
</HTML>
You can set the value like this:
document.forms[0].elements[0].value=document.forms[0].elements[1].value;
If the form is first and the text box is the first element of the form, otherwise you can specify the index instead.
If you don't know the index, you can loop through all elements, check for the value "First," and make changes accordingly.
In order to achieve the desired outcome, you will need to create a loop.
let elements = document.getElementsByTagName('input');
let index = 0;
for(index = 0; index < elements.length; index++){
if(elements[index].value == "First"){
elements[index].value = "Second";
}
}
