jQuery：.focus（）上的太多递归

Question

I am using the jQuery .focus() method to focus on an element through a remote script in asp.net. I am getting an error about too much recursion.

What am I doing wrong?

asp.net code :

Response.Write("<script>$('#ledger_name').focus();</script>");

html

<input type="text" id="account_name" name="account_name" />

js for auto complete

$("#account_name").autocomplete({
    source: account_master,
    minLength: 1,
    minChars: 0,
    width: 350,
    mustMatch: 0,
    selectFirst: true,
    matchContains: false,
    autoFocus: true,
    autoFill: false,
    change: function (event, ui) {
        if (!ui.item) {
            $(this).val('');
        }
    },
    select: function (event, ui) {
        $("#account_name").val(ui.item.label);
        $("#account_name_code").val(ui.item.id);
        $("#account_name_parent").val(ui.item.parent);

        //$('#ledger_name').focus();
        return true;
    }

});

jquery ui

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js" type="text/javascript"></script>

it's giving an error in jquery-ui.min.js file on calling $('#ledger_name').focus(); in autocomplete

Answer 1

To have textbox with id of "ledger_name" focused upon page load, just add this JavaScript in your .aspx page:

<script type="text/javascript">
$(document).ready(function() {
    $("#ledger_name").focus();
});
</script>

No need to do that from the code behind.

Probably focusing it also triggers the autocomplete, so you can't focus it from within the autocomplete itself.
