I want a button to be disabled initially. Once a condition is met, I want to enable the button. I tried the below and the button is not getting enabled.
<button class="search btn right-align search-button disabled" id="view-btn">
Hello
</button>
$('#submit_query').click(function(){
document.getElementById("myBtn").disabled = false;
}
If you use jQuery is simpler:
$('#submit_query').click(function(){
$("#myBtn").attr("disabled","false");
});<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.3.1.min.js"></script>
<button class="search btn right-align search-button disabled" id="myBtn">
Hello
</button>
<button id="submit_query">Submit</button>Make sure your #ids match your HTML button controls and that you are bringing in jQuery. Then to enable an element you want to do this:
$('#enable').click(function(){
$("#view-btn").removeAttr("disabled");
});
and to disable:
$('#disable').click(function(){
$("#view-btn").attr("disabled","true");
});
For working example: http://jsbin.com/xigeyixoji/edit?html,output
Try this:
function myFunction() {
document.getElementById("myBtn").disabled = false;
}<html>
<body>
<button id="myBtn" disabled>My Button</button>
<p>Click the button below to disable the button above.</p>
<button onclick="myFunction()" >Try it</button>
</body>
</html>In the code provided the id for the button element is "view-btn" however the JavaScript code is using getElementById using "myBtn".
Also, the button is assigned the 'disabled' class which may or may not actually disable the button. "disabled" is a separate attribute from class.
Additionally, the JavaScript is using jQuery to assign the click handler. The standard way to use jQuery to enable a control is:
$("#view-btn").prop("disabled", false );
<button class="search btn right-align search-button" disabled id="view_btn">
Hello
</button>
<button class="search btn right-align search-button" id="submit_query">
click me
</button>
var myHTML = document.querySelector('#submit_query');
myHTML.onclick = function() {
console.log(1);
document.getElementById("view_btn").disabled = false;
};
