I'm trying to make an image slider. I have an array of objects like this:
var slides = [
{
img: 'images/one.jpg',
text: 'First Image'
},
{
img: 'images/two.jpg',
text: 'Second Image'
}
];
I need to have the functionality to add more images into the image slider. Hence I need to obtain the file path of the image I will be uploading and push that file path into this slides
array.
I have gone through this SO answer, which effectively teaches how to upload and display an image, but my needs are different.
HTML
<div id="slide-container">
</div>
<div id="panel-container">
<form>
<label>
<span>Image Text</span>
<input type="text" class="form-control" id="image-related-text">
</label>
<label>
<span>Duration</span>
<input type="text" class="form-control" id="time-duration">
</label>
<div id="d">
<input type="file" id="image-upload">
</div>
<button id="add" disabled="true">Add to Container</button>
</form>
</div>
JS
var global_image_url = "";
// add the image and the relevant text in the slider on click of this button
$('#add').click(function(){
var imageRelatedText = $('#image-related-text').val();
var timeDuration = $('#time-duration').val();
// a new object to be pushed inside the 'slides' array
var temp_obj = {
img: 'nothing for now :|', //this should contain the image url
text: imageRelatedText
};
})
$('#image-upload').change(function(){
global_image_url = readUrl(this);
console.log(global_image_url);
});
// this function gets called when an image file is chosen
function readUrl(input){
var img = $('<img>');
var local_image_url = ""; // thought I would store the file path in this variable
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
local_image_url = JSON.stringify(e.target.result);
img.attr('src', e.target.result);
img.attr('height','100%');
img.attr('width','97%');
}
reader.readAsDataURL(input.files[0]);
}
console.log(local_image_url); // chrome developer tools freezes
return local_image_url;
}
I thought e.target.result
would give the url but that's not the case. It's just another object (printed in the console once).
So how do I achieve my requirements?
Thanks!
