[JQuery]学习总结

1. Jquery 选择多个class 如何精确匹配

$("div[class='class1 class2']").css({ "margin-bottom": "0px" });
$("input[name='selectedConstractorSid'][type='text']").val();//取值
$("input[name='selectedConstractorSid'][type='text']").val(“赋给你一个值”);//赋值值

 2. 隔行换色

function RefreshTableColor() {
    var trs = $("#yourID tbody tr");
    for (var i = 0; i < trs.length; i++) {
        if (i % 2 == 0) {
            trs[i].style.backgroundColor = "#e0e0df";
            console.log("use");
        } else {
            trs[i].style.backgroundColor = "#fff";
        }
    }
};

3. 操作table

$(document).on("click","#yourID tbody tr td",function () {
            var yourSid = $(this).parent().find("td:first div").html();
            console.log(yourSid );
});

 4. Ajax cache在1.2默认为true

$.ajax({
  url: "test.html",
  cache: false, //或者设置true
  success: function(html){
    $("#results").append(html);
  }
});
