I have the following code:
// I am filling the data of the "MultiSelectDialog_List" div using javascript like this: var s = ''; // JSON string ----- YOU NEED TO ADD AN EXAMPLE OF S var jsonData = JSON.parse(s); for (var i = 0; i < jsonData.length; i++) { // Hold the original list $("#MultiSelectDialog_List").append("<input type='checkbox' id ='" + jsonData[i][idProp] + "' value='" + jsonData[i][idProp] + "' data-value='" + jsonData[i][nameProp].toLowerCase() + "' > <label data-value ='" + jsonData[i][nameProp].toLowerCase() + "' id ='lbl" + jsonData[i][idProp] + "'>" + jsonData[i][nameProp] + "</label> <br/>"); } // Then I am using this script to hide some content: var enteredText = $("#MultiSelectDialog_Search").val(); var ary = $("input[type='checkbox']:not([data-value*='" + enteredText.toLowerCase() + "'])"); for (var i = 0; i < ary.length; i++) { $("#" + ary[i]["id"]).hide(); }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="multiSelectDialog" title="Select"> <input type="text" id="MultiSelectDialog_Search" name="MultiSelectDialog_Search" onchange="multiSelectDialog_Search_TextChanged()" /> <div id="MultiSelectDialog_List" data-value=""> <!--The data will goes here--> </div> <input type="hidden" name="MultiSelectDialog_Values" id="MultiSelectDialog_Values" /> <button id="MultiSelectDialog_Submit" onclick="multiSelectDialog_SubmitButton_Click()">Submit</button> </div>
The problem is that the content of the div are not redrawen correctly after hiding some elements. Check the image:
When hiding elements, see the gaps
How should I refresh the div? I tried to use hide() and show(), fadein(). but did not work.
Try something like this
$(document).ready(function(){
// use localStorage.removeItem('show'); to unset an item
var show = localStorage.getItem('show');
if(show === 'true'){
$('#MultiSelectDialog_List').show();
}
$("#btn").click(function(event){
event.preventDefault();
$('#MultiSelectDialog_List').show();
localStorage.setItem('show', 'true');
});
});
// I am filling the data of the "MultiSelectDialog_List" div using javascript like this: var s = '[{"EnName":"Device Linked Officer","ArName":"Device Linked Officer","Status":false,"Project":"CMS","ID":"ROL29","IsOrderNumRequired":true,"IsTimeInterval":false,"IsHealthCare":true,"isBiller":false},{"EnName":"pharmacist","ArName":"pharmacist","Status":false,"Project":"CMS","ID":"ROL30","IsOrderNumRequired":true,"IsTimeInterval":false,"IsHealthCare":true,"isBiller":false},{"EnName":"Store & Pharmacy","ArName":"Store & Pharmacy","Status":false,"Project":"CMS"}]'; // JSON string ----- YOU NEED TO ADD AN EXAMPLE OF S var jsonData = JSON.parse(s); var idProp = 'ID'; var nameProp = 'EnName'; for (var i = 0; i < jsonData.length; i++) { // Hold the original list $("#MultiSelectDialog_List").append("<input type='checkbox' id ='" + jsonData[i][idProp] + "' value='" + jsonData[i][idProp] + "' data-value='" + jsonData[i][nameProp].toLowerCase() + "' > <label data-value ='" + jsonData[i][nameProp].toLowerCase() + "' id ='lbl" + jsonData[i][idProp] + "'>" + jsonData[i][nameProp] + "</label> <br/>"); } // Then I am using this script to hide some content: function multiSelectDialog_SubmitButton_Click() { var enteredText = $("#MultiSelectDialog_Search").val(); var ary = $("input[type='checkbox']:not([data-value*='" + enteredText.toLowerCase() + "'])"); for (var i = 0; i < ary.length; i++) { $("#" + ary[i]["id"]).hide(); } } function multiSelectDialog_Search_TextChanged() { // TODO }

I've updated the given snippet a little bit to try to achieve a working code.
Your problem is, that its not really clear what idProp
or nameProp
is (so I decided on my own).
Another problem you will face:
You do hide stuff, but you never get it back. Once a checkbox got hidden its gone for good.
