Dynamic javascript using JQuery?
My code is as follows:
<script>
$(document).ready(function() {
var tagCounter=0;
$("#tag-add-button").click(function () {
var text = $("#tagadd").val();
$("#set-tags").append("<input type='text' id='tag"+tagCounter+"' READONLY>");
$("#tag"+tagCounter).val(text);
$("#tagadd").val("");
tagCounter++;
});
});
</script>
This does the following:
When tag-add-button is clicked, it takes the text fro开发者_StackOverflow中文版m the inputbox (tagadd) and puts it in a new inputbox thats appended to the set-tags div. The tagadd inputbox is then made blank.
The problem I'm having, is I want each input box to have its own remove button. But I don't see how the javascript can be generated for that when there can be an unlimited number of input boxes...
Any ideas?
Put the input element inside of a div or span, and make the remove button a sibling of the input element. Then, in the onclick handler of the button, just do something like $(this).parent().remove()
This has the effect of removing both the input element, and the remove button itself
Rather than using an id (#tag-add-button
), use classes and then use the each function of jQuery and traverse to the appropriate elements.
$(document).ready(function() {
var tagCounter=0;
$("#tag-add-button").click(function () {
var text = $("#tagadd").val();
$("#set-tags").append('<input type="text" id="tag'+tagCounter+'" READONLY /><span class="remove">Remove</span>');
$("#tag"+tagCounter).val(text);
$("#tagadd").val("");
tagCounter++;
});
$('span.remove').bind('click',function(){
$(this).prev('input').andSelf().remove();
});
});
