javascript - Add and remove inputs dynamicly with a other input -


i searched lot this, can find +1 -1 solutions. want set number of inputs other input this:

//enter number of inputs (1 start-value) <input type="text" size="3" maxlength="3" id="count" name="count" value="1">  //display number of inputs (1 @ start) <input type="text" size="30" maxlength="30" id="input_1" name="input_1">

when user writes 5 in first field, form should this:

//enter number of inputs (1 start-value) <input type="text" size="3" maxlength="3" id="count" name="count" value="1">  //display number of inputs (1 @ start) <input type="text" size="30" maxlength="30" id="input_1" name="input_1"> <input type="text" size="30" maxlength="30" id="input_2" name="input_2"> <input type="text" size="30" maxlength="30" id="input_3" name="input_3"> <input type="text" size="30" maxlength="30" id="input_4" name="input_4"> <input type="text" size="30" maxlength="30" id="input_5" name="input_5">

how can make this? must use js?

here's simple javascript snippet doesn't make use of frameworks:

function addinputs() {     var count = parseint(document.getelementbyid("count").value);     (var = 2; <= count; i++) {         document.getelementbyid('moreinputs').innerhtml += '<input type="text" name="input_' + + '" id="input_' + + '" />';     } }

in example have add container (div) id 'moreinputs'. however, when calling function more once, not work (e.g. can increase number of input not decrease)
