如何在html中保存日期[关闭]

Question

i am new to html and php. i am trying to calculate difference between two dates. although i have managed to make a JS function for calculation the difference. but it need two date variables to calculate the difference.

i have use <input type="date"> to make an input of date from user. but now the problem i am facing is that how can i store the vale in the textbox(the date in it) into a variable ? is there any $_POST method to get the date stored into a variable ?

Answer 1

Use an event Javascript and pass the new value parameter.

HTML:

<input type="date" name="dateOne" value="" onChange="setDate(this.value);"/>

Javascript:

var date;
function setDate(val) {
    date = val;
}

Edit (based on comment)

For set the variable into a form, create an input type hidden (or other).

<input id="jsValue" type="hidden" name="jsValue" value="" />

In Javascript put the value into your input

document.getElementById("jsValue").value = yourVariable;

To see a result in your web page, create a span tag (or other)

<span id="seeYourVariable"></span>

In Javascript use the property innerHtml to put your variable into the tag

document.getElementById("seeYourVariable").innerHTML = yourVariable;
