How Can I Move Selected Option In Multiselect Up And Down By Buttons Using Jquery?

I have select 123<Solution 1: Update: Fixed code for multiple options selected, based on @patrick dw's suggestion.$(document).ready(function(){ $('input[type="button"]').click(function(){ var$op = $('#select2 option:selected'), $this = $(this); if($op.length){ ($this.val() == 'Up') ? $op.first().prev().before($op) : $op.last().next().after($op); } }); }); CopyTest it here »No need to use inline onclick="" event listeners. jQuery takes full control of separating presentation from functionality.Solution 2: if you do not use jqueryfunction moveUp(){ varselect = document.getElementById("columnOrder"); var options = select && select.options; var selected = []; for (var i = 0, iLen = options.length; i < iLen; i++) { if (options[i].selected) { selected.push(options[i]); } } for (i = 0, iLen = selected.length; i < iLen; i++) { var index = selected[i].index; if(index == 0){ break; } var temp = selected[i].text; selected[i].text = options[index - 1].text; options[index - 1].text = temp; temp = selected[i].value; selected[i].value = options[index - 1].value; options[index - 1].value = temp; selected[i].selected = false; options[index - 1].selected = true; } } function moveDown(){ varselect = document.getElementById("columnOrder"); var options = select && select.options; var selected = []; for (var i = 0, iLen = options.length; i < iLen; i++) { if (options[i].selected) { selected.push(options[i]); } } for (i = selected.length - 1, iLen = 0; i >= iLen; i--) { var index = selected[i].index; if(index == (options.length - 1)){ break; } var temp = selected[i].text; selected[i].text = options[index + 1].text; options[index + 1].text = temp; temp = selected[i].value; selected[i].value = options[index + 1].value; options[index + 1].value = temp; selected[i].selected = false; options[index + 1].selected = true; } } CopySolution 3: functionup() { var selected = $("#select2").find(":selected"); var before = selected.prev(); if (before.length > 0) selected.detach().insertBefore(before); } functiondown() { var selected = $("#select2").find(":selected"); var next = selected.next(); if (next.length > 0) selected.detach().insertAfter(next); } CopySolution 4: I created a jquery plugin for this: https://github.com/UziTech/jquery.moveSelected.jsusage:$("button#up").click(function(){ $("select").moveSelectedUp(); }); $("button#down").click(function(){ $("select").moveSelectedDown(); }); Copyhttp://jsfiddle.net/UziTech/qr5qfhgg/Solution 5: here is the same idea as the previously-posted non-jquery example, but with some strategic code re-use. My need was to have the buttons always operate on the same select element, named "cols". You could put "sel" as a parameter of the moveUp() and moveDown() functions if you want something more generic.functionmoveUp() { var sel = document.getElementById("cols"); var i1=0, i2=1; while (i2 < sel.options.length) { swapIf(sel,i1++,i2++); } } functionmoveDown() { var sel = document.getElementById("cols"); var i1=sel.options.length-1, i2=i1-1; while (i1 > 0) { swapIf(sel,i1--,i2--); } } var swapVar = ''; functionswapIf(sel,i1,i2) { if ( ! sel[i1].selected && sel[i2].selected) { swapVar = sel[i2].text; sel[i2].text = sel[i1].text; sel[i1].text = swapVar; swapVar = sel[i2].value; sel[i2].value = sel[i1].value; sel[i1].value = swapVar; sel[i1].selected = true; sel[i2].selected = false; } } Copy Share Post a Comment for "How Can I Move Selected Option In Multiselect Up And Down By Buttons Using Jquery?"
