JavaScript語法-將變量傳遞給函數

Question

var testvar = "something";

//only one of the following 3 lines were uncommented while testing:
var myinsert = '<span class="green myCursor" 
                   onClick="getproblemsadmin(testvar)">
                   Test
                </span>'; //doesn't pass testvar to function

var myinsert = '<span class="green myCursor" 
                   onClick="getproblemsadmin(\'testvar\')">
                   Test
                </span>'; //doesn't pass testvar to function

var myinsert = "<span class='green myCursor' 
                   onClick='getproblemsadmin(\"testvar\")\'>
                   Test
                </span>"; //doesn't pass testvar to function

$('.someclass').html(myinsert); //jquery works and this works (tested)

有沒有辦法將變量傳遞給這樣的函數？

Answer 1

你是說這個變量的值嗎？

var myinsert = "<span class='green myCursor' onClick='getproblemsadmin(\""+testvar+"\")\'>Test</span>";

語法：

var myinsert = "string" + variable + "string";
var myinsert = 'string' + variable + 'string';

Answer 2

您可以嘗試創建span元素，然后綁定click事件：

$('<span class="green myCursor">Test</span>').click(function()
{
    getproblemsadmin('testvar')
});

或者，如果您想真正獲得jQuery'esk，則可以編寫：

$('<span />').addClass('green myCursor').text('test').click(function()
{
    getproblemsadmin('testvar')
});

Answer 3

如果我理解正確，您正在尋找一種將變量傳遞給函數的方法，該函數將返回包含標記代碼的構造字符串？ 像這樣嗎

var testvar = "something";

var myinsert = work_horse(testvar);
$('.someclass').html(myinsert);

function work_horse(testvar){
    return '<span class="green myCursor" onClick="getproblemsadmin(' + testvar + ')">Test</span>';
}​
