HTML + javascript mouse over, mouseout, onclick not working in firefox.
- by lucky
Hello Everyone,
My question is to get onMouseover,onMouseout,onMousedown,onClick on a table row. For which i am calling javascript userdefined functions.
onMouseover --- Background color should change.
onMouseout --- Reset to original color
onClick --- First column checkbox/radio button should be set and background color should change
onMousedown --- background color should change.
My code in html is:-
<tr onMouseOver="hover(this)" onMouseOut="hover_out(this)" onMouseDown="get_first_state(this)" onClick="checkit(this)" >
and the methods in javascripts are:-
var first_state = false;
var oldcol = '#ffffff';
var oldcol_cellarray = new Array();
function hover(element) {
if (! element) element = this;
while (element.tagName != 'TR') {
element = element.parentNode;
}
if (element.style.fontWeight != 'bold') {
for (var i = 0; i<element.cells.length; i++) {
if (element.cells[i].className != "no_hover") {
oldcol_cellarray[i] = element.cells[i].style.backgroundColor;
element.cells[i].style.backgroundColor='#e6f6f6';
}
}
}
}
// -----------------------------------------------------------------------------------------------
function hover_out(element) {
if (! element) element = this;
while (element.tagName != 'TR') {
element = element.parentNode;
}
if (element.style.fontWeight != 'bold') {
for (var i = 0; i<element.cells.length; i++) {
if (element.cells[i].className != "no_hover") {
if (typeof oldcol_cellarray != undefined) {
element.cells[i].style.backgroundColor=oldcol_cellarray[i];
} else {
element.cells[i].style.backgroundColor='#ffffff';
}
//var oldcol_cellarray = new Array();
}
}
}
}
// -----------------------------------------------------------------------------------------------
function get_first_state(element) {
while (element.tagName != 'TR') {
element = element.parentNode;
}
first_state = element.cells[0].firstChild.checked;
}
// -----------------------------------------------------------------------------------------------
function checkit (element) {
while (element.tagName != 'TR') {
element = element.parentNode;
}
if (element.cells[0].firstChild.type == 'radio') {
var typ = 0;
} else if (element.cells[0].firstChild.type == 'checkbox') {
typ = 1;
}
if (element.cells[0].firstChild.checked == true && typ == 1) {
if (element.cells[0].firstChild.checked == first_state) {
element.cells[0].firstChild.checked = false;
}
set_rowstyle(element, element.cells[0].firstChild.checked);
} else {
if (typ == 0 || element.cells[0].firstChild.checked == first_state) {
element.cells[0].firstChild.checked = true;
}
set_rowstyle(element, element.cells[0].firstChild.checked);
}
if (typ == 0) {
var table = element.parentNode;
if (table.tagName != "TABLE") {
table = table.parentNode;
}
if (table.tagName == "TABLE") {
table=table.tBodies[0].rows;
//var table = document.getElementById("js_tb").tBodies[0].rows;
for (var i = 1; i< table.length; i++) {
if (table[i].cells[0].firstChild.checked == true && table[i] != element) {
table[i].cells[0].firstChild.checked = false;
}
if (table[i].cells[0].firstChild.checked == false) {
set_rowstyle(table[i], false);
}
}
}
}
}
function set_rowstyle(r, on) {
if (on == true) {
for (var i =0; i < r.cells.length; i++) {
r.style.fontWeight = 'bold';
r.cells[i].style.backgroundColor = '#f2f2c2';
}
} else {
for ( i =0; i < r.cells.length; i++) {
r.style.fontWeight = 'normal';
r.cells[i].style.backgroundColor = '#ffffff';
}
}
}
It is working as expected in IE.
But coming to firefox i am surprised on seeing the output after so much of coding.
In Firefox:--
onMouseOver is working as expected. color change of that particular row.
onClick -- Setting the background color permenantly..eventhough i do onmouseover on different rows. the clicked previous row color is not reset to white. -- not as expected
onclick on 2 rows..the background of both the rows is set..Only the latest row color should be set. other rows that are selected before should be set back..not as expected i.e if i click on all the rows..background color of everything is changed...
Eventhough i click on the row. First column i.e radio button or checkbox is not set..
Please help me to solve this issue in firefox. Do let me know where my code needs to be changed...
Thanks in advance!!
