如何在输入字段中提交Javascript值

Question

Simply, how can I do this?

<input type="hidden" value="some javascript value" />

I have a form whereby when a user clicks on Add More , more input fields are added via javascript.

I'm also using javascript-declared values to track and limit the number of fields a user can add.

I need a way for my php code to retrieve these javascript values .

Answer 1

From the button you must be calling a javascript to add these fields dynamically. Simply append the code to that function to hand over these values to the field.

<input id="myinputfield[]" type="hidden" value="" />
<script>
function addOneMore(){
      var newField = // code to add one more field
      newField.value = newValue; 
}
</script>

Will solve your purpose.

Answer 2

the question is a bit vague, but i will give it a go

try adding a name as an array and then you can use get or post

<input name="myjavascriptinputs[]" type="hidden" value="some javascript value" />

in your php you will be able to use

foreach($_GET['myjavascriptinputs'] as $ajavascriptinput)

Answer 3

Use append

$('#hidden').val('my Text');

input field should be

<input type="hidden" id="hidden"/>
