Populate form from JSON.parse - javascript

I am trying to re-populate a form from some values in localStorage. I can't quite manage the last part to get the loop to populate my name and values.
function loadFromLocalStorage() {
PROCESS_SAVE = true;
var store = localStorage.getItem(STORE_KEY);
var jsn = JSON.parse(store);
console.log(jsn);
if(store.length === 0) {
return false;
}
var s = jsn.length-1;
console.log(s);
for (var i = 0; i < s.length; i++) {
var formInput = s[i];
console.log(s[i]);
$("form input[name='" + formInput.name +"']").val(formInput.value);
}
}
Could I get some pointers please.

Your issue is in this section of code.
var s = jsn.length-1;
console.log(s);
for (var i = 0; i < s.length; i++) {
You are setting s to the length of the jsn array minus 1, then using it as if it were jsn. I think you intended something like this.
function loadFromLocalStorage() {
PROCESS_SAVE = true;
var store = localStorage.getItem(STORE_KEY);
var jsn = JSON.parse(store);
console.log(jsn);
if(store.length === 0) {
return false;
}
for (var i = 0; i < jsn.length; i++) {
var formInput = jsn[i];
console.log(jsn[i]);
$("form input[name='" + formInput.name +"']").val(formInput.value);
}
}

JavaScript Json row undefined for TreeView

I have a question. When querying my Json object, although i have my Field as same name and all Json rows available give me an error that is undefined.
//e.g: row.DepParentId
Bellow is my code. Am I missing some tag?
function convert(rows) {
debugger;
function exists(rows, parent) {
for (var i = 0; i < rows.length; i++) {
if (rows[i].DepId === parent) return true;
}
return false;
}
var nodes = [];
// get the top level nodes
for (var i = 0; i < rows.length; i++) {
var row = rows[i];
if (!exists(rows, row.DepParentId)) {
nodes.push({
id: row.DepId,
name: row.Title
});
}
}
var toDo = [];
for (var i = 0; i < nodes.length; i++) {
toDo.push(nodes[i]);
}
while (toDo.length) {
var node = toDo.shift();
// the parent node
// get the children nodes
for (var i = 0; i < rows.length; i++) {
var row = rows[i];
if (row.DepParentId == node.Id) {
var child = {
Id: row.DepId,
Name: row.Title
};
if (node.options) {
node.options.push(child);
} else {
node.options = [child];
}
toDo.push(child);
}
}
}
return nodes;
}
My Json example for one row picked from Firefox
"{"DepId":7,"DepParentId":3,"Title":"OTT"}"
Thanks for helping

thanks all for helping, it's working now, the problem was the JSON.stringify() was returning only an [Object] so when you use JSON.parse() generates a sintax error.
function onLoaded() {
var itemsCount = items.get_count();
for (var i = 0; i < itemsCount; i++) {
var item = items.itemAt(i);
var dep = JSON.stringify(item.get_fieldValues());
deps.push(dep);
}
So, i had to change the format to be valid to parse like this
var dt = "[" + deps + "]";
var ret = JSON.parse(dt);
Thanks

Gridview search filter with paging

function Search_Gridview(strKey, strGV) {
var strData = strKey.value.toLowerCase().split(" ");
var tblData = document.getElementById(strGV);
var rowData;
for (var i = 1; i < tblData.rows.length; i++) {
rowData = tblData.rows[i].innerHTML;
var styleDisplay = 'none';
for (var j = 0; j < strData.length; j++) {
if (rowData.toLowerCase().indexOf(strData[j]) >= 0)
styleDisplay = '';
else {
styleDisplay = 'none';
break;
}
}
tblData.rows[i].style.display = styleDisplay;
}
}
i have a gridview and i want to add search filter on it. This code works correctly but search just one page not all rows. How i make this, i discovered but i didn't solve this.

Protractor:How to store values in array and then to do sorting

I need to sort list strings under the table ,so for that i have written following lines of code but on console i am not getting any values:
var j = 9;
var rows = element.all(by.repeater('row in renderedRows'));
var column = element.all(by.repeater('col in renderedColumns'));
expect(rows.count()).toEqual(5); //here its printing number of rows
expect(column.count()).toEqual(5); //here its printing number of columns
var arr = [rows.count()];
for (var i = 0; i < rows.count(); i++) {
console.log("aai" + i);
if (i = 0) {
//var columnvalue=column.get(9).getText();
var columnvalue = column.get(9).getText().then(function(ss) {
return ss.trim();
arr[i] = ss.trim(); //here it will save the value first value of column
console.log("value1" + arr[i]);
expect(arr[i]).toEqual('DN');
console.log("aa" + ss.trim());
});
} else {
var j = j + 8;
var columnvalue = column.get(j).getText().then(function(ss) {
return ss.trim();
arr[i] = ss.trim(); //here it will save the other values of column
console.log("value" + arr[i]);
expect(arr[i]).toEqual('DN');
console.log("ab" + ss.trim());
});
}
}
Sorting_Under_Table: function(col){
test = [];
var m;
var dm = 0;
element(by.xpath('//div[#class="ngHeaderScroller"]/div['+col+']')).click();
element.all(by.repeater('row in renderedRows')).then(function(row) {
m = row.length;
for (i = 1; i <= row.length; i++)
{
user_admin_table_name = browser.driver.findElement(by.xpath('//div[#class="ngCanvas"]/div['+i+']/div['+col+']'));
user_admin_table_name.getText().then(function(text) {
var test_var1 = text.toLowerCase().trim();
test.push(test_var1);
var k = test.length
if (k == m){
for (j = 0; j < test.length; j++){
test.sort();
d=j+1;
user_admin_table_name1 = browser.driver.findElement(by.xpath('//div[#class="ngCanvas"]/div['+d+']/div['+col+']'));
user_admin_table_name1.getText().then(function(text1) {
var test_var2 = text1.toLowerCase().trim();
if (test_var2 == test[dm]){
expect(test_var2).toEqual(test[dm]);
dm = dm +1;
}else {
expect(test_var2).toEqual(test[dm]);
log.error("Sorting is not successful");
dm = dm +1;
}
});
}
}
});
}
});
},
You can use this code for sorting and verifying is it sorted or not
I'm not sure how your above example is doing any sorting, but here's a general solution for trimming and then sorting:
var elementsWithTextToSort = element.all(by.xyz...);
elementsWithTextToSort.map(function(elem) {
return elem.getText().then(function(text) {
return text.trim();
});
}).then(function(trimmedTexts) {
return trimmedTexts.sort();
}).then(function(sortedTrimmedTexts) {
//do something with the sorted trimmed texts
});

avoid sorting in the JSP pages

var sortitems = 1;
function move(fbox, tbox, all)
{
for ( var i = 0; i < fbox.options.length; i++)
{
if (!all && fbox.options[i].selected && fbox.options[i].value != "")
{
var no = new Option();
no.value = fbox.options[i].value;
no.text = fbox.options[i].text;
tbox.options[tbox.options.length] = no;
fbox.options[i].value = "";
fbox.options[i].text = "";
}
else
{
if (all && fbox.options[i].value != "")
{
var no = new Option();
no.value = fbox.options[i].value;
no.text = fbox.options[i].text;
tbox.options[tbox.options.length] = no;
fbox.options[i].value = "";
fbox.options[i].text = "";
}
}
}
BumpUp(fbox);
if (sortitems)
SortD(tbox);
checkSelectAll();
}
This move function is getting called after clicking on the button, then it will call the sort method where sorting is happening by alphabetically. So we dont need to sort we need to populate the data as it is from the left side box to right side box and vice versa, but sorting is happening. Please help out be here.
function SortD(box)
{
var temp_opts = new Array();
var temp = new Object();
for ( var i = 0; i < box.options.length; i++)
{
temp_opts[i] = box.options[i];
}
for ( var x = 0; x < temp_opts.length - 1; x++)
{
for ( var y = (x + 1); y < temp_opts.length; y++)
{
if (temp_opts[x].value > temp_opts[y].value)
{
temp = temp_opts[x].text;
temp_opts[x].text = temp_opts[y].text;
temp_opts[y].text = temp;
temp = temp_opts[x].value;
temp_opts[x].value = temp_opts[y].value;
temp_opts[y].value = temp;
}
}
}
for ( var i = 0; i < box.options.length; i++)
{
box.options[i].value = temp_opts[i].value;
box.options[i].text = temp_opts[i].text;
}
}
Depends on the bumpup box function. The elements are moving from one box to another. It will replace the element with empty space and move to top and do for all the elements. Please help out me here
Thanks in advance
function BumpUp(box)
{
for ( var i = 0; i < box.options.length; i++)
{
if (box.options[i].value == "")
{
for ( var j = i; j < box.options.length - 1; j++)
{
box.options[j].value = box.options[j + 1].value;
box.options[j].text = box.options[j + 1].text;
}
var ln = i;
break;
}
}
if (ln < box.options.length)
{
box.options.length -= 1;
BumpUp(box);
}
}
Maybe it's just me, but it's hard to see what the issue is here.
If it is simply that SortD(tbox) is being called within the move() function, that's because
sortitems is set to 1 right at the top of the code. The value of sortitems is never changed anywhere else, so this conditional is always true and SortD is always called.
if (sortitems)
SortD(tbox);

remove null value in javascript

am having script with working condition but many for loop is there so any way to do this...to simplify this ...am new to script kindly help on this....
function change()
{
//document.getElementById("Geography").options[7]=new Option("", "newval", true, false);
var geo = document.getElementById("Geography").options;
var zon = document.getElementById("zone").options;
var coun = document.getElementById("country").options;
for (var i = 0; i < geo.length; i++)
{
if (geo[i].innerHTML == "Null Value" || geo[i].innerHTML == "")
{
document.getElementById("Geography").options[i] = null;
}
}
for (var i = 0; i < coun.length; i++)
{
alert("Loop1" + i);
if (coun[i].innerHTML == "Null Value")
{
document.getElementById("country").options[i] = null;
}
}
for (var i = 0; i < zon.length; i++)
{
//alert("Loop1" + i);
if (zon[i].innerHTML == "Null Value")
{
document.getElementById("zone").options[i] = null;
}
}
}
To remove an option, call removeChild() on the parent element.
var geoSel = document.getElementById("Geography");
var geo = geoSel.options;
for (var i = geoSel.options.length-1; i >= 0; i--) {
if (geo[i].innerHTML == "Null Value" || geo[i].innerHTML == "") {
geo.removeChild(geo[i]);
}
}
I count down instead of up because removing a child will cause the indexes of all the following children to be shifted down. In a count-up loop, that will cause elements to be skipped.
use this UPDATED DEMO
function change(){
var optionsArr = [];
optionsArr.push(document.getElementById("Geography").options);
optionsArr.push(document.getElementById("zone").options);
optionsArr.push(document.getElementById("country").options);
var optArrlenght = optionsArr.length;
for ( var j = 0; j < optArrlenght; j++){
var options = optionsArr[j];
var optionslength = options.length;
for (var i = 0; i < optionslength; i++)
{
if (options[i].innerHTML == "Null Value" || options[i].innerHTML == "")
{
options[i].remove();
i--;
optionslength--;
}
}
}
}
change();
