Append Javascript

**sudjo** · 04-28-2008, 05:12 AM

Hi all,
I have a simple problem, but I can't seem to figure this out for the life of me.

Problem:
1. Using Javascript and PHP
2. Move values from onClick links to text boxes
3. Want to call the function (superpaste) to create a custom sql statement. Every thing works other than the calling of the superpaste function and its workings.

http://utite.org/resumeinfo/easysql.php#

function superpaste(){
var writingblock = document.myQueryForm.query;
var degree = document.first_form.degree.value;
var interest = document.first_form.interest.value;
var region = document.first_form.region.value;
var experience = document.first_form.experience.value;
var writingblock.value = "Select * from Resume WHERE degree_program = '";
var writingblock.value =+ degree;
var writingblock.value =+ "' AND interest = '";
var writingblock.value =+ interest;
var writingblock.value =+ "' AND region ='";
var writingblock.value =+ region;
var writingblock.value =+ " ' AND experience = '";
var writingblock.value =+ experience;
var writingblock.value =+ "' ;";
}
}

//////////////////////////////////////////////////////////////////////////////////
/*
This function tests to see if something has been entered in the query.
If empty then an alert box appears and the form submission is halted
*/
function isQuery() {
var myForm = document.myQueryForm;
if ( myForm.query.value == 0 ) {
alert("There is no query.\nPlease enter a query.");
myForm.query.focus();
return false;
}
return true;
}

Actually there are other problems with the page, but perhaps you were messing around with it since you posted. The superpaste function should be:

Code:

function superpaste(){
	var writingblock = document.myQueryForm.query;
	var degree = document.first_form.degree.value;
	var interest = document.first_form.interest.value;
	var region = document.first_form.region.value;
	var experience = document.first_form.experience.value;
	writingblock.value = "Select * from Resume WHERE degree_program = '";
	writingblock.value += degree;
	writingblock.value += "' AND interest = '";
	writingblock.value += interest;
	writingblock.value += "' AND region ='";
	writingblock.value += region;
	writingblock.value += " ' AND experience = '";
	writingblock.value += experience;
	writingblock.value +=  "' ;";
	}

Aside from the obvious changes (dropped the redundant and illegal multiple var declarations) I also reversed =+ to +=. The former is math assignment meaning literally:

equals positive

The later (when valid) is concatenation or addition, depending upon the values. If strings, as is the case here, concatenation.

And finally, perhaps least obvious, I dropped an extra closing curly bracket:

}

from the end of the function.

Now another thing wrong with the page is this (its onclick event is so full of errors that it is basically meaningless in javascript):

HTML Code:

<input type="button" 
onclick="Select * from Resume WHERE degree_program = 'document.first_form.degree.value' AND interest = 'document.first_form.interest.value' AND region ='document.first_form.region.value' AND experience = 'document.first_form.experience.value';" 
value="Call function">

It probably should be (now that superpaste works):

HTML Code:

<input type="button" 
onclick="superpaste();" 
value="Call function">

There still could be other issues.
