I have a link in my html page like the on below :
<a id="save_report" href="javascript:void(0);" title="Save Report" onclick="javascript:enterReportNameToSave(<?php echo $upload_count?>,<?php echo $startOffset;?>,<?php echo $affiliateId; ?>);">Save Report <img height="16" width="16" style="vertical-align: bottom;" src="/img/icn_export.gif" alt="export"></a>
As, you can see , I need to send few parameters to the function enterReportNameToSave and at the same time , I need to invoke a callback function as well to handle a popup .
My enterReportNameToSave() function invocation will be something like :
function enterReportNameToSave(count,startOffset,user_id,f)
{
//Some logic to set a div element based on the parameter values
f()//This will be the implementation of my call function
{
//Here I need to invoke the popup logic
}
}
Here I'm confused with the correct implementation of this , I mean what's the correct开发者_如何学Go way to implement the scenario. Please help.
Hope you find this useful.
function enterReportNameToSave(count,startOffset,user_id,f)
{
$("#yourdivid").html("<h1>Show Loading bar or load up your actual html data here</h1>").load("use_this_if_data_needs_fetching_from_remote.php","count="+count+"&f="+f,function() {
alert("I am just a useless popup and have popped up after the div is populated");
});
}
Suppose you have various callback functions in Javascript:
function f1(count, offset, uid) {
alert("count=" + count);
}
function f2(count, offset, uid) {
alert("offset" + offset);
}
// etc
In PHP you can pass the name of the callback function to your constructed onclick function as a further parameter:
onclick="javascript:enterReportNameToSave(<?php echo $upload_count; ?>,
<?php echo $startOffset; ?>, <?php echo $affiliateId; ?>,
<?php echo $callback_name; ?> );">
The concrete value of the onclick string would be e.g.
onclick="javascript:enterReportNameToSave(10, 20, 1234, f1);"
The Javascript function enterReportNameToSave()
looks like:
function enterReportNameToSave(count, startOffset, user_id, f) {
// use parameters count, startOffset, user_id
// call callback function f:
f(count, startOffset, user_id);
}
