I am having trouble removing a class that I have added using a checkbox. The checkbox is checked to begin with. When it is unchecked by the user it adds a "hideRect" class with classed('hideRect', true);
this works great BUT when I check the box again the class doesn't go away.
Here is my code:
this.$node.append('input')
.attr('type', 'checkbox')
.attr('checked', true)
.attr('value', 'med')
.on('click', () => this.updateRectLine());
}
private updateRectLine() {
//var rect = this.$node.getElementsByClassName('.MEDICATION');
var cbMed = this.$node.attr("checked");
if (cbMed !== true){
this.$node.selectAll(".MEDICATION").classed('hideRect', true);
}
else if (cbMed == true){
this.$node.selectAll(".MEDICATION").classed('hideRect', false);
}
}
thanks in advance!
You need to update the below function like this
private updateRectLine() {
var cbMed = this.$node.select("input[type='checkbox']").prop("checked");
if (!cbMed)
this.$node.selectAll(".MEDICATION").classed('hideRect', true);
else
this.$node.selectAll(".MEDICATION").classed('hideRect', false);
}
.attr() function only returns the value the checkbox was initialized to, to check for a checkbox's check state, you want to use property checked present on check box elements

I can't uncheck a checkbox after I checked it (all via JS/Jquery).
Code:
//Works perfect
function showL(labelObj)
{
var cb = $(labelObj).prev()[0];
$(cb).prop('checked', true);
}
//Does NOT work
function hideL(labelObj)
{
var cb = $(labelObj).next()[0];
//$(cb).attr('checked', false);
$(cb).prop('checked', false);
}
update
It's the same object in both functions:
You can just do.
$('input[type="checkbox"]').on('click', function{
var propState = $(this).prop('checked'); // grab the checkbox checked state.
propState === true ? propState = false : propState = true; // ternary operation. If box is checked uncheck it. if it is not checked check it.
}
It will work on all checkboxes.
Is it possible to identify if the value of radio button has not changed?
Currently I am trying to change the confirmation message of submit button on button changed, and do not want any message if the value has not changed. I have something like this now:
$('input[type="radio"]').change(function() {
var selected = $('input:checked[type="radio"]').val();
if(selected == 'true') {
$("#submit_button").data("confirm", "foo");
} else if(selected == 'false') {
$('#fee').hide();
$("#submit_button").data("confirm", "bar");
}
This will change confirm message to foo if button selected is true, and bar if button selected is false. However, what if I want to return nothing (no message), if radio button by default is true, and selected is true?
You can start a variable outside the event:
var radioChanged = 0;
And, in your event increase it:
$(':radio').change(function() {
radioChanged += 1;
// your code ...
});
Then, later on:
if (radioChanged > 0) {
alert('Change function occurred ' + radioChanged + ' times.');
} else {
alert('Radio button not changed.');
}
As i understand your expected behaviour, check if any radio has no more its default checked value:
$('form').on('submit', function() {
var anyRadioChanged = !!$(this).find('input[type="radio"]').filter(function() {
return $(this).is(':checked') != this.defaultChecked;
}).length; // '!!' to get boolean but it doesn't really matter here
if(anyRadioChanged) {
// show message(???)
}
})
you can hide message element just adding display: none to it or use jquery hide method
$('#someElementId').hide();
or
$('#someElementId').css("display","none")
Working on jquery clone with my current code everthing works fine.
first scenario if user select other from the drop down the text
field gets enabled
Second scenario if user click addmore button div gets clone
perfectly with id when user select other both Original and clone
textfield gets enabled actually it should be only the cloned should
get enabled not the enabled
Here is the current Jquery code
var i=1;
$(document).on("click", ".edu_add_button", function () {
var i=$('.cloned-row1').length;
$(".cloned-row1:last").clone(true).insertAfter(".cloned-row1:last").attr({
'id': function(_, id) { return id + i },
'name': function(_, name) { return name + i }
}).end().find('[id]').val('').attr({ 'id': function(_, id) { return id + i }
});
$(".cloned-row1:last").find(".school_Name").attr('disabled', true).val('');
if(i < $('.cloned-row1').length){
$(this).closest(".edu_add_button").removeClass('btn_more edu_add_button').addClass('btn_less btn_less1');
}
i++;
return false;
});
$(document).on('click', ".btn_less1", function (){
var len = $('.cloned-row1').length;
if(len>1){
$(this).closest(".cloned-row1").remove();
}
});
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
$('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(".school_Name").prop('disabled', false);
$(".school_Name").val('');
}else{
$(".school_Name").prop('disabled', true);
}
});
$(document).on('change', '.txt_degreName', function (){
var cur = $('.txt_degreName').index($(this));
$('.degree_Description').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$("#degree_Description").prop('disabled', false);
$("#degree_Description").val('');
}else{
$("#degree_Description").prop('disabled', true);
}
});

The issue comes be cause you are using class selector directly. You need apply value only to the text box which belongs in the same container. Use closest() to find the parent.
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
var container = $(this).closest('.container-fluid');
$('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(".school_Name", container).prop('disabled', false);
$(".school_Name", container).val('');
}else{
$(".school_Name", container).prop('disabled', true);
}
});

You need to refer proper element that has to be disabled and enabled.
Take the sibling of select's parent and find the input element to be disabled as below:
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
$(this).closest('.col-xs-6').next('.col-xs-6').find('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(this).closest('.col-xs-6').next('.col-xs-6').find(".school_Name").prop('disabled', false);
$(this).closest('.col-xs-6').next('.col-xs-6').find(".school_Name").val('');
}else{
$(this).closest('.col-xs-6').next('.col-xs-6').find(".school_Name").prop('disabled', true);
}
});
From what you did, you actually change every fields with class .school_Name, to achieve what you want you can add $(this).parents(".row").find(".class_name") so it only change the current div.
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
$('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(this).parents(".row").find(".school_Name").prop('disabled', false);
$(this).parents(".row").find(".school_Name").val('');
}else{
$(this).parents(".row").find(".school_Name").prop('disabled', true);
}
});

You can do it this way with targeting specific item using parent() and next() selector and also i prefer to access specific field instead of index(such as eq) for input.
var schoolObj = $(this).parent().next().find(".school_Name");
schoolObj.val($(this).val());
if ($(this).val() == "other") {
schoolObj.prop('disabled', false);
schoolObj.val('');
} else {
schoolObj.prop('disabled', true);
}

You can have a look for jquery traversing:
parent: https://api.jquery.com/parent/
Next: https://api.jquery.com/next/
Find: https://api.jquery.com/find/
and for full traversing: https://api.jquery.com/category/traversing/
I have the following scripts that it puts the data-length and data-width on textbox based on drop down question
My question is how I make the .width and .length textboxes readonly based on dropodown selection as below?
$(document).ready(function() {
$('select.cargo_type').change(function() {
var eur1width = $('select.cargo_type').find(':selected').data('width');
$('.width').val(eur1width);
//make width textbox readonly
var eur1length = $('select.cargo_type').find(':selected').data('length');
$('.length').val(eur1length);
//make length textbox readonly
});
});
You can use prop to set textbox readonly.
$('.width').val(eur1width).prop('readonly', true);
$('.length').val(eur1length).prop('readonly', true);
To remove readonly you can set the readonly property to false;
$('.width').val(eur1width).prop('readonly', false);
$('.length').val(eur1length).prop('readonly', false);
UPDATE
if (eur1width == 'myVal') {
$('.width').val(eur1width).prop('readonly', true);
} else {
$('.width').val(eur1width).prop('readonly', false);
}
Use prop('readonly',true/false); on the element. Like,
if(eur1width == 'checking_val'){
$('.width').val(eur1width).prop('readonly', true);
}else{
$('.width').val(eur1width).prop('readonly', false);
}
OR
To toggle the property
$('.width').val(eur1width).prop('readonly', !$(this).prop('readonly'));
I want to make the checkbox work more or less like a radio button in this instance. This is what I have so far. I would like to be able to do this in the treeCheckboxClicked() function so that it would just uncheck all the remaining checkboxs then check the one that was selected.
buildTocTree: function (cp1) {
var self = this;
var toc = new TOC({
checkboxes: false,
enableDelete: true,
deleteRecursive: true,
showRoot: false,
checkBoxes: false,
}, self._viewId + '_tocTree');
toc.on("checkBoxClick", dojo.hitch(this, "treeCheckboxClicked"));
},
treeCheckboxClicked: function (e) {
if (e.checked) {
if (e.subLayers || e.name === 'GISLayer')
this.selectedLayerValue('');
else if (e.layerInfos)
this.selectedLayerValue('');
else
this.selectedLayerValue(e.name);
if (this.selectedLayerValue() != '')
this._selectedGISSourceLayer = e;
else
this._selectedGISSourceLayer = '';
}
}
Without knowing the internal details of the TOC widget, especially its DOM, it's difficult to know how to query all checkboxes within its template. Assuming your treeCheckboxClicked is already getting called, and e.target is the checkbox element itself, the following code should get you close to your desired functionality:
if (e.checked) {
query('checkbox', self.domNode).forEach(function (checkbox) {
checkbox.checked = checkbox != e.target;
});
//...
}
Note: This assumes the dojo/query module has been loaded.
Are you using agsjs.TOC? They have a handler included to do this for you. In the examplesat http://gmaps-utility-gis.googlecode.com/svn/tags/agsjs/latest/examples/toc.html they toggle the function off and on with a button, but you can make it default on and include the following snippet in your tree declaration. (replace DynaLayer 1 with your layer)
toc.on('toc-node-checked', function(evt){
// when check on one layer, turn off everything else on the public safety service.
if (evt.checked && evt.rootLayer && evt.serviceLayer && evt.rootLayer == dynaLayer1){
evt.rootLayer.setVisibleLayers([evt.serviceLayer.id])
}
