How to clear HTML input textbox via Javascript

I am using the same input textbox to collect multiple values.

After collecting the first input, I will clear the field by calling

document.getElementById("textbox").value= "";

On the surface, above snippet appears to clear the textbox. But when I blur the textbox by clicking elsewhere, the old value reappears.

MORE CODES >>>

My HTML >>

<input id="textbox" placeholder="Start">

Javascript >>

After getting the first input, I like to reset the input value >>>

document.getElementById("textbox").value= "";
document.getElementById("textbox").setAttribute("placeholder","End");

This is how I do my data collection >>> The same textbox is first used to collect a Google "place", and then subsequently to collect some user entered comment. In addition to collecting the data, someFunction() also try to clear the textbox by calling .value= ""

google.maps.event.addListener(textbox, "place_changed", function() {
    someFunction();
});

I have practically implemented and used this solution whch is already suggested by my friend above:

document.getElementById("textbox").setAttribute("placeholder","End");

So, this works for me pretty well.(context:"placeholder" attribute used)

Here is something i found googling fast for an answer; i think you can play around indeed with onFocus() a bit:

<input type="text" value="Click here to clear text" onfocus="if(!this._haschanged){this.value=''};this._haschanged=true;"/>

It may require a bit of usage of onBlur as well.

Also some other pointer, to get you going with jQuery if you want.

Looks like your input's value is stored in separate variable to be used for some other actions. So you should maybe check your code and clear thar variable.
