Text Changed and javascript confirm box
-
I have a textbox which is created dynamically in page_load. TextBox tb = new TextBox(); tb.id = "ID1"; tb.text = GetfromDB(); tb.TextChanged +=new EventHandler(tb_TextChanged); Now i want to add a javascript confirmbox as tb.Attributes.Add("onchange","javascript:return confirm('Data has Changed. Click OK To Continue');"); If the user clicks ok then continue to tb_TextChanged function and if user clicks cancel i want to restore the previous value of textbox. How can i write the javascript function? Thanks

Basically when a postback occurs, everything in the page gets recreated again. If it is not posted back you need to somewhere hold the initial values and show to the items. You can make a global object say
var myarray = {};
myarray["textbox1"] = document.getElementById("textbox1").value;
..
..
..When you restore, set the value from myarray to actual controls.
document.getElementById("textbox1").value = myarray.textbox1;
...
...
...what is the problem with that. If the page is not posted back you can do this easily. :thumbsup:

of course there is. You might use
onfocus = "javascript:myarray[this.id]=this.value"to initializemyarraywith initial value if you want. No big deal, do it whatever you feel like. :rose:Abhishek Sur **Don't forget to click "Good Answer" if you like this Solution.
