问题描述
我有HTML表格,我需要选择一行并将其第一个单元格ID发送到一个按钮, onclick
按钮将选定的值发送到Javascript中的函数。如何实现这一点?
test.html < table id =table>
< tr>
< td> 1 Ferrari F138< / td>
< td> 1 000€< / td>
< td> 1 200€< / td>
< / tr>
< tr>
< td> 2 Ferrari F138< / td>
< td> 1 000€< / td>
< td> 1 200€< / td>
< / tr>
< tr>
< td> 3 Ferrari F138< / td>
< td> 1 000€< / td>
< td> 1 200€< / td>
< / tr>
< / table>
< input type =buttonid =tstvalue =OKonclick =fnselect()/>
test.js :
var table = document.getElementById('table'),
selected = table.getElementsByClassName('selected');
table.onclick = highlight;
function highlight(e){
if(selected [0])selected [0] .className ='';
e.target.parentNode.className ='selected';
}
function fnselect(){
var $ row = $(this).parent()。find('td');
var clickeedID = $ row.eq(0).text();
alert(clickeedID);
}
test.css :
td {border:1px #DDD solid; padding:5px; cursor:pointer;}
.selected {
background-color:brown;
color:#FFF;
}
这是一个小问题 JSFIDDLE
我需要将所选行的第一个单元格值发送到javascript函数。但是当用户选择一行并点击确定按钮时,我应该发送值到函数。如何做到这一点?
解决方案
$(#table tr)。 function(){
$(this).addClass('selected')。siblings()。removeClass('selected');
var value = $(this).find('td:first' ).html();
alert(value);
});
$('。ok')。on('click',function(e){
alert($(#table tr.selected td:first)。html );
});
演示:
I have HTML table where I need to select a row and send its first cell ID to a button and
onclick
of the button send the selected value to a function in Javascript. How can I achieve this?test.html :
<table id="table"> <tr> <td>1 Ferrari F138</td> <td>1 000€</td> <td>1 200€</td> </tr> <tr> <td>2 Ferrari F138</td> <td>1 000€</td> <td>1 200€</td> </tr> <tr> <td>3 Ferrari F138</td> <td>1 000€</td> <td>1 200€</td> </tr> </table> <input type="button" id="tst" value="OK" onclick="fnselect()" />
test.js :
var table = document.getElementById('table'), selected = table.getElementsByClassName('selected'); table.onclick = highlight; function highlight(e) { if (selected[0]) selected[0].className = ''; e.target.parentNode.className = 'selected'; } function fnselect(){ var $row=$(this).parent().find('td'); var clickeedID=$row.eq(0).text(); alert(clickeedID); }
test.css :
td {border: 1px #DDD solid; padding: 5px; cursor: pointer;} .selected { background-color: brown; color: #FFF; }
This is a fiddle of my problem JSFIDDLE
I need to send the selected row's first cell value to a javascript function. But when the user selects a row and clicks on 'OK' button I should send the value to the function. How to do this?
解决方案$("#table tr").click(function(){ $(this).addClass('selected').siblings().removeClass('selected'); var value=$(this).find('td:first').html(); alert(value); }); $('.ok').on('click', function(e){ alert($("#table tr.selected td:first").html()); });
